Chapter 11: Advanced Percentages (Successive, Reverse, Applications)
Estimated Reading Time: 25 minutes
Chapter 11 FAQs
What are successive percentage changes and how do I calculate them?
Successive percentage changes occur when a value changes by multiple percentages one after another.
Formula for two successive changes:
- Overall change = a + b + ab/100 (where a and b are percentages, positive for increase, negative for decrease)
- If a = 10% increase and b = 20% increase: Overall = 10 + 20 + (10×20)/100 = 30 + 2 = 32% increase
- If a = 10% increase and b = 10% decrease: Overall = 10 - 10 - (10×10)/100 = 0 - 1 = -1% (1% decrease)
For three or more changes: Multiply (1 + p1/100) × (1 + p2/100) × (1 + p3/100) – 1, then × 100%
How do I solve reverse percentage problems?
Reverse percentage problems ask you to find the original value when the final value and percentage change are given.
Formulas:
- If price increased by x%: Original = Final × 100/(100 + x)
- If price decreased by x%: Original = Final × 100/(100 - x)
- If population increased from P to Q in n years at r%: P = Q / (1 + r/100)^n
Example: After a 25% increase, the price is ₹500. Original = 500 × 100/125 = ₹400.
Trap: Do NOT simply subtract 25% from 500 (that would be 375, which is wrong).
What are percentage application problems in elections and population?
Common application problems:
Election problems:
- Total votes = Valid votes + Invalid votes
- Winner's votes = Loser's votes + Margin
- If x% votes are invalid, valid votes = Total × (100 - x)/100
Population problems:
- Population after n years = P × (1 + r/100)^n (growth)
- Population after n years = P × (1 - r/100)^n (decay)
- Difference between two years = P × r/100 × (1 + r/100)
Mini Case Study: Successive Discount vs Successive Increase
Question: A shirt price is ₹1000. It is increased by 20%, then decreased by 20%. What is the final price?
Common mistake: Thinking final price is ₹1000 (since 20% up and 20% down cancel).
Correct calculation:
- After 20% increase: 1000 × 1.2 = ₹1200
- After 20% decrease: 1200 × 0.8 = ₹960
- Net change = -4% (not 0%)
Using successive formula: 20 - 20 - (20×20)/100 = 0 - 4 = -4% → ₹960
Chapter 11 Practice Questions
Practice Question 1: A number is increased by 30% and then decreased by 30%. Find the net change.
Answer: 30 - 30 - (30×30)/100 = -9% (9% decrease).
Practice Question 2: After a 20% increase, the price is ₹600. Find the original price.
Answer: 600 × 100/120 = ₹500.
Practice Question 3: A population increases at 10% per year. If current population is 1,21,000, what was it 2 years ago?
Answer: 1,21,000 / (1.1)² = 1,21,000 / 1.21 = 1,00,000.
Chapter 11 Summary
What are the key takeaways from Chapter 11?
Chapter 11 covered advanced percentages:
- Successive percentage: a + b + ab/100 – order doesn't matter.
- Reverse percentage: Original = Final × 100/(100 ± x).
- Election problems: Account for invalid votes before calculating winner/loser percentages.
- Population problems: Use compound interest formula for growth/decay.
- Trap: A% increase followed by A% decrease does NOT return to original – net decrease of (A²/100)% .
Keywords: successive percentage, reverse percentage, election problems, population growth, percentage change trap
Chapter 12: Profit, Loss, Discount, and Marked Price (Advanced)
Estimated Reading Time: 25 minutes
Chapter 12 FAQs
What are the advanced profit-loss formulas with multiple items?
When dealing with multiple items with different profit/loss percentages:
Overall profit/loss:
- Total CP = CP1 + CP2 + ...
- Total SP = SP1 + SP2 + ...
- Overall profit% = (Total SP - Total CP)/Total CP × 100%
When two items sold at same SP:
- Item 1 profit% = x%, Item 2 loss% = x%
- Overall loss% = (x²/100)%
- Example: Two items sold at ₹100 each, one at 20% profit, one at 20% loss → Overall loss = 400/100 = 4%
How do I solve marked price and discount problems with successive discounts?
Relationships:
- SP = MP × (100 - D%)/100
- MP = SP × 100/(100 - D%)
- Profit% on CP = (SP - CP)/CP × 100%
- Discount% on MP = (MP - SP)/MP × 100%
Successive discounts:
- Single equivalent discount = d1 + d2 - (d1×d2)/100
- For three discounts: First combine two, then combine with third
Example: Successive discounts of 20% and 10% = 20 + 10 - 200/100 = 28% single discount
What are the formulas for profit percentage on CP vs SP?
Profit on Cost Price:
- SP = CP × (100 + P%)/100
- Profit = P% of CP
Profit on Selling Price:
- If profit is 20% on SP, then SP = CP × 100/80
- CP = SP × (100 - P%)/100 where P% is profit on SP
Conversion formula:
- If profit% on CP = x%, then profit% on SP = (100x)/(100 + x)%
- If profit% on SP = y%, then profit% on CP = (100y)/(100 - y)%
Mini Case Study: Profit-Loss on Multiple Items
Question: A shopkeeper sells two items at same price. One at 20% profit, one at 20% loss. Find overall profit/loss.
Solution:
- Let SP of each = ₹120
- Item 1 (20% profit): CP1 = 120 × 100/120 = ₹100
- Item 2 (20% loss): CP2 = 120 × 100/80 = ₹150
- Total CP = 100 + 150 = ₹250, Total SP = 120 + 120 = ₹240
- Overall loss = ₹10, Loss% = 10/250 × 100% = 4%
Chapter 12 Practice Questions
Practice Question 1: Find single equivalent discount for 30% and 10% successive discounts.
Answer: 30 + 10 - (30×10)/100 = 40 - 3 = 37%.
Practice Question 2: If profit is 25% on CP, what is profit on SP?
Answer: (100×25)/(100+25) = 2500/125 = 20%.
Practice Question 3: Two items sold at ₹200 each. One at 25% profit, one at 25% loss. Find overall.
Answer: Overall loss = (25²)/100 = 625/100 = 6.25% loss.
Chapter 12 Summary
What are the key takeaways from Chapter 12?
Chapter 12 covered advanced profit-loss-discount:
- Multiple items: Calculate total CP and total SP separately.
- Same SP, different profit/loss%: Overall loss = (x²/100)%.
- Successive discounts: Single equivalent = d1 + d2 - d1d2/100.
- Profit on CP vs SP: Use conversion formulas.

Chapter 13: Simple & Compound Interest (Installments, CI-SI Difference)
Estimated Reading Time: 25 minutes
Chapter 13 FAQs
What are the installment formulas for simple interest?
Installment problems ask for the equal periodic payment to repay a loan.
For Simple Interest (SI):
- Installment = (Amount × 100)/(100T + R × T(T-1)/2)
- Where T = number of installments, R = rate% per year
Alternative method: Each installment is discounted to present value using SI formula.
Example: Borrow ₹10,000 at 10% SI, repay in 2 equal annual installments. Let installment = x. 1st installment discounted: x/(1 + 0.1) = x/1.1. 2nd: x/(1 + 0.2) = x/1.2. Sum = 10,000 → x = 10,000/(1/1.1 + 1/1.2) = approximately ₹5,238.
What are the installment formulas for compound interest?
For compound interest, use present value discounting:
- PV of installment = Installment / (1 + r)^n
- Loan amount = Sum of PV of all installments
- Installment = Loan amount × r × (1 + r)^n / [(1 + r)^n - 1]
Example: ₹1,00,000 loan at 10% CI, repay in 3 equal annual installments. r = 0.1, n = 3. Installment = 1,00,000 × 0.1 × (1.1)³ / [(1.1)³ - 1] = 1,00,000 × 0.1 × 1.331 / (1.331 - 1) = 13,310 / 0.331 ≈ ₹40,210
What is the difference between CI and SI for 2 and 3 years?
These formulas help solve problems without calculating full CI and SI:
Difference for 2 years:
- CI - SI = P × (R/100)²
Difference for 3 years:
- CI - SI = P × (R/100)² × (300 + R)/100
Example: P = ₹10,000, R = 10%, T = 2 years. CI - SI = 10,000 × (10/100)² = 10,000 × 0.01 = ₹100
Check: SI = 10,000×0.1×2 = ₹2,000; CI = 10,000×1.21 - 10,000 = ₹2,100; Difference = ₹100.
What are half-yearly and quarterly compounding formulas?
When interest is compounded more frequently than annually:
Half-yearly:
- Rate = R/2, Time = 2T
- Amount = P × (1 + R/200)^(2T)
Quarterly:
- Rate = R/4, Time = 4T
- Amount = P × (1 + R/400)^(4T)
Example: P = ₹10,000, R = 10% p.a., T = 1 year.
- Annual: 10,000 × 1.1 = ₹11,000
- Half-yearly: 10,000 × (1.05)² = 10,000 × 1.1025 = ₹11,025
- Quarterly: 10,000 × (1.025)⁴ = 10,000 × 1.1038 = ₹11,038
Mini Case Study: CI vs SI Difference
Question: The difference between CI and SI for 2 years on ₹5,000 at a certain rate is ₹72. Find the rate.
Solution:
- CI - SI = P × (R/100)²
- 72 = 5000 × (R/100)²
- (R/100)² = 72/5000 = 0.0144
- R/100 = √0.0144 = 0.12
- R = 12%
Chapter 13 Practice Questions
Practice Question 1: Find CI on ₹10,000 at 10% p.a. for 2 years compounded half-yearly.
Answer: Amount = 10,000 × (1.05)⁴ = 10,000 × 1.2155 = ₹12,155. CI = ₹2,155.
Practice Question 2: The difference between CI and SI for 2 years on ₹8,000 is ₹20. Find rate.
Answer: 20 = 8000 × (R/100)² → (R/100)² = 20/8000 = 0.0025 → R/100 = 0.05 → R = 5%.
Practice Question 3: A loan of ₹50,000 at 10% SI is repaid in 2 equal annual installments. Find installment.
Answer: x = 50,000 × 100 / (100×2 + 10×2×1/2) = 5,000,000 / (200 + 10) = 5,000,000/210 = ₹23,809.52.
Chapter 13 Summary
What are the key takeaways from Chapter 13?
Chapter 13 covered advanced simple and compound interest:
- Installments (SI): Installment = (Amount × 100)/(100T + R × T(T-1)/2).

Chapter 14: Ratio, Proportion, and Partnership (Complex Problems)
Estimated Reading Time: 25 minutes
Chapter 14 FAQs
What are the advanced ratio and proportion shortcuts for BBA entrances?
Advanced ratio problems involve multiple ratios, comparison of ratios, and applications in mixtures.
Key formulas and shortcuts:
- Duplicate ratio of a:b = a² : b²
- Triplicate ratio of a:b = a³ : b³
- Sub-duplicate ratio = √a : √b
- Sub-triplicate ratio = ∛a : ∛b
- Componendo: If a/b = c/d, then (a+b)/b = (c+d)/d
- Dividendo: If a/b = c/d, then (a-b)/b = (c-d)/d
- Componendo and Dividendo: (a+b)/(a-b) = (c+d)/(c-d)
Example: If a/b = 2/3, find (a+b)/(a-b). Using Componendo-Dividendo: (2+3)/(2-3) = 5/(-1) = -5.
How do I solve problems with multiple ratios?
When given ratios a:b, b:c, c:d, find a:b:c:d by making the common terms equal.
Method:
- a:b = 2:3, b:c = 4:5. Find a:b:c.
- Multiply first ratio by 4: a:b = 8:12
- Multiply second ratio by 3: b:c = 12:15
- Therefore a:b:c = 8:12:15
For three ratios a:b, b:c, c:d: Multiply to find common terms and combine step by step.
What are the formulas for partnership problems with changing capitals?
Partnership problems test profit sharing based on capital and time.
Basic partnership formula:
- Profit ratio = (Capital1 × Time1) : (Capital2 × Time2)
When capitals change over time:
- Calculate weighted capital = sum of (Capital × Time period)
- Profit ratio = Weighted Capital1 : Weighted Capital2
Example: A invests ₹50,000 for 6 months, then ₹60,000 for 6 months. B invests ₹80,000 for 12 months. A's weighted capital = (50,000×6) + (60,000×6) = 3,00,000 + 3,60,000 = 6,60,000 B's weighted capital = 80,000×12 = 9,60,000 Profit ratio = 6,60,000 : 9,60,000 = 66 : 96 = 11 : 16
What are problems on income, expenditure, and savings?
These problems use the relationship: Income = Expenditure + Savings
Common patterns:
- If income ratio of A and B is a:b and expenditure ratio is c:d, and savings are equal, find income.
- If incomes are in ratio a:b, expenditures in ratio c:d, and savings in ratio e:f.
Example: A and B have incomes in ratio 5:3 and expenditures in ratio 9:5. If each saves ₹2,000, find their incomes.
Let incomes be 5x and 3x. Expenditures be 9y and 5y. Savings: 5x - 9y = 2000, 3x - 5y = 2000. Solving: Multiply second by 3: 9x - 15y = 6000. Multiply first by 5: 25x - 45y = 10000. Solve: x = 4000, y = 2000. Incomes: ₹20,000 and ₹12,000.
Mini Case Study: Partnership with Changing Capitals
Question: A starts business with ₹60,000. After 4 months, B joins with ₹40,000. After another 4 months, C joins with ₹50,000. Profit at year end is ₹45,000. Find share of each.
Solution:
- A's capital × time = 60,000 × 12 = 7,20,000
- B's capital × time = 40,000 × 8 = 3,20,000
- C's capital × time = 50,000 × 4 = 2,00,000
- Ratio = 7,20,000 : 3,20,000 : 2,00,000 = 72 : 32 : 20 = 18 : 8 : 5
- Total parts = 31. A's share = (18/31)×45,000 = ₹26,129; B's = (8/31)×45,000 = ₹11,613; C's = (5/31)×45,000 = ₹7,258
Chapter 14 Practice Questions
Practice Question 1: If a:b = 3:4 and b:c = 6:7, find a:c.
Answer: a:c = (3×6):(4×7) = 18:28 = 9:14.
Practice Question 2: If a/b = 4/5, find (a+b)/(a-b) using Componendo-Dividendo.
Answer: (4+5)/(4-5) = 9/(-1) = -9.
Practice Question 3: A and B invest ₹40,000 and ₹60,000 for 1 year. A withdraws ₹10,000 after 6 months. Find profit ratio.
Answer: A's weighted = (40,000×6) + (30,000×6) = 2,40,000 + 1,80,000 = 4,20,000. B's = 60,000×12 = 7,20,000. Ratio = 4,20,000:7,20,000 = 42:72 = 7:12.

Chapter 15: Averages, Mixtures, and Allegations (Advanced)
Estimated Reading Time: 25 minutes
Chapter 15 FAQs
What are the advanced average formulas for BBA entrances?
Advanced average problems involve weighted averages, averages with replacements, and averages of groups.
Key formulas:
- Weighted average: = (n1×a1 + n2×a2)/(n1 + n2)
- Average of two groups combined: Overall avg = (n1×avg1 + n2×avg2)/(n1 + n2)
- When one value is replaced: New sum = Old sum - removed + added; New avg = New sum/n
- Difference caused by replacement: Change in sum = New value - Old value; Change in avg = Change in sum/n
Example: Average age of 20 students is 18. A student of age 20 leaves, a new student of age 22 joins. New average? New sum = (20×18) - 20 + 22 = 360 - 20 + 22 = 362. New avg = 362/20 = 18.1.
What is the alligation rule and how do I apply it?
Alligation is used to find the ratio in which two or more ingredients at different prices should be mixed to get a mixture of a desired price.
Alligation rule:
- (Quantity of cheaper)/(Quantity of dearer) = (Mean price - Cheaper price)/(Dearer price - Mean price)
Example: Mix rice at ₹40/kg and ₹60/kg to get mixture at ₹50/kg. Ratio = (50-40):(60-50) = 10:10 = 1:1.
For three ingredients: Use repeated alligation or form equations.
How do I solve removal and replacement problems?
Removal and replacement problems involve removing a portion of a mixture and replacing it with another liquid.
Formula for repeated replacements:
- Final quantity of original liquid = x × (1 - y/x)^n
- Where x = initial quantity, y = quantity removed each time, n = number of operations
Example: A container has 40L of milk. 4L is removed and replaced with water. This is done 3 times. Find final milk quantity. Final milk = 40 × (1 - 4/40)³ = 40 × (0.9)³ = 40 × 0.729 = 29.16L.
For different quantities removed each time: Apply step by step.
What are problems on mean price and profit percentage in mixtures?
These problems combine mixture alligation with profit percentage.
Formula:
- If a mixture is sold at profit of P%, then CP of mixture = SP × 100/(100 + P)
- Then use alligation to find mixing ratio
Example: Two types of rice at ₹30/kg and ₹40/kg are mixed and sold at ₹44/kg at 10% profit. Find mixing ratio.
CP of mixture = 44 × 100/110 = ₹40/kg. Using alligation: Ratio = (40-30):(40-40) = 10:0. This means only dearer rice is used (all ₹40/kg rice).
Mini Case Study: Removal and Replacement
Question: A vessel contains 60L of milk. 6L is removed and replaced with water. This is done twice. Find final milk quantity.
Solution:
- After first operation: Milk = 60 × (1 - 6/60) = 60 × 0.9 = 54L
- After second operation: Milk = 54 × (1 - 6/60) = 54 × 0.9 = 48.6L
- Using formula: 60 × (1 - 0.1)² = 60 × 0.81 = 48.6L

Chapter 16: Time, Speed, Distance (Relative Speed, Trains, Boats, Races)
Estimated Reading Time: 30 minutes
Chapter 16 FAQs
What are the advanced time, speed, distance formulas?
Advanced TSD problems involve multiple moving objects, variable speeds, and complex scenarios.
Basic formulas:
- Speed = Distance/Time, Distance = Speed × Time, Time = Distance/Speed
- km/h to m/s: multiply by 5/18; m/s to km/h: multiply by 18/5
Average speed for different distances: Total Distance/Total Time (not simple average)
For equal distances at speeds v1 and v2: Avg Speed = 2v1v2/(v1 + v2)
For equal times at speeds v1 and v2: Avg Speed = (v1 + v2)/2
How do I solve relative speed problems?
Relative speed is the effective speed of two objects moving with respect to each other.
Formulas:
- Same direction: Relative speed = |v1 - v2|
- Opposite direction: Relative speed = v1 + v2
Time to meet: Time = Distance between them / Relative speed
Example: Two trains 200m and 300m long run parallel. Speeds 60 km/h and 40 km/h in same direction. Time to cross each other?
- Relative speed = 60 - 40 = 20 km/h = 20 × 5/18 = 50/9 m/s
- Total distance = 200 + 300 = 500m
- Time = 500 / (50/9) = 500 × 9/50 = 90 seconds
How do I solve train problems?
Train problems involve length of train, crossing platforms/poles, and crossing other trains.
Key formulas:
- Time to cross a pole/tree = Length of train / Speed
- Time to cross a platform/bridge = (L train + L platform) / Speed
- Time to cross a man walking = L train / (Speed of train ± Speed of man)
- Time to cross another train (opposite) = (L1 + L2)/(v1 + v2)
- Time to cross another train (same direction) = (L1 + L2)/|v1 - v2|
How do I solve boats and streams problems?
Boats and streams involve speed of boat in still water and speed of current.
Formulas:
- Downstream speed (D) = Boat speed (u) + Stream speed (v)
- Upstream speed (U) = Boat speed (u) - Stream speed (v)
- Boat speed in still water = (D + U)/2
- Stream speed = (D - U)/2
Time to go down and up: Total time = d/(u+v) + d/(u-v)
If boat travels equal distance up and down: Average speed = (2uv)/(u+v) ×? Actually average speed = (u² - v²)/u
How do I solve races and circular track problems?
Race problems involve competitions where participants start together and finish at different times.
Key concepts:
- If A beats B by x meters in a race of L meters, then while A runs L meters, B runs (L - x) meters.
- Ratio of speeds = L : (L - x)
- Time taken by A to finish = Time taken by B to run (L - x)
Circular track: Time for first meeting = Track length / Relative speed
Number of meetings in time T: T × Relative speed / Track length
Mini Case Study: Train Crossing Problem
Question: A 180m long train runs at 54 km/h. How long to cross a 220m platform?
Solution:
- Speed = 54 km/h = 54 × 5/18 = 15 m/s
- Total distance = L train + L platform = 180 + 220 = 400m
- Time = Distance/Speed = 400/15 = 26.67 seconds
Chapter 16 Practice Questions
Practice Question 1: Two trains 150m and 200m long run at 72 km/h and 54 km/h in opposite directions. Time to cross each other?
Answer: Relative speed = 72+54 = 126 km/h = 126×5/18 = 35 m/s. Total distance = 150+200=350m. Time = 350/35 = 10 seconds.
Practice Question 2: Boat speed in still water is 12 km/h, stream speed 4 km/h. Find downstream and upstream speeds.
Answer: Downstream = 12+4=16 km/h, Upstream = 12-4=8 km/h.
Practice Question 3: A 200m train crosses a pole in 10 seconds. Find its speed in km/h.

Chapter 17: Time and Work (Alternate Days, Efficiency, Pipes & Cisterns)
Estimated Reading Time: 30 minutes
Chapter 17 FAQs
What are the advanced time and work formulas?
Advanced time and work problems involve multiple workers, efficiency ratios, and alternate day work patterns.
Basic formulas:
- Work = Rate × Time
- If A takes T days, A's rate = 1/T work/day
- A and B together = 1/T1 + 1/T2 work/day
- Time together = 1/(1/T1 + 1/T2) = (T1 × T2)/(T1 + T2)
For three workers: Time together = 1/(1/T1 + 1/T2 + 1/T3)
When two workers together take T12 days: 1/T12 = 1/T1 + 1/T2
How do I solve efficiency-based problems?
Efficiency problems compare how fast workers complete work.
Key relationships:
- If A is k times as efficient as B, then T_A = T_B/k
- If A is x% more efficient than B, then A's rate = B's rate × (100 + x)/100
- Time ratio = Inverse of efficiency ratio
Example: A is twice as efficient as B. If B takes 20 days alone, A takes 10 days alone.
Wages distribution: Wages are proportional to work done = Rate × Time
- W1/W2 = (R1 × T1)/(R2 × T2)
- If workers work for same time, wages ratio = efficiency ratio
How do I solve alternate day work problems?
Alternate day problems involve workers taking turns day by day.
Method:
- Calculate work done in 2 days (A day 1, B day 2) = 1/T1 + 1/T2
- Number of complete cycles = floor(Total work / Work per cycle)
- Remaining work done by next worker
Example: A takes 4 days, B takes 6 days. They work on alternate days starting with A. Find total time.
- Work in 2 days = 1/4 + 1/6 = 3/12 + 2/12 = 5/12
- After 2 cycles (4 days): work done = 10/12, remaining = 2/12 = 1/6
- Day 5 (A works): A's rate = 1/4 = 3/12, but only 2/12 needed
- Time needed = (2/12)/(3/12) × 1 day = 2/3 day
- Total time = 4 + 2/3 = 4.67 days
How do I solve pipes and cisterns problems?
Pipes and cisterns are time and work problems with filling and emptying pipes.
Key formulas:
- Inlet pipe: Positive rate (fills the cistern)
- Outlet pipe: Negative rate (empties the cistern)
- Net rate = Sum of all rates (inlet +, outlet -)
- Time to fill/empty = Total capacity / Net rate
Example: Pipe A fills in 4 hours, Pipe B empties in 6 hours. If both open, net rate = 1/4 - 1/6 = 3/12 - 2/12 = 1/12. Time to fill = 12 hours.
When pipes open for different times: Calculate work done by each and sum.
Mini Case Study: Alternate Days with Three Workers
Question: A, B, C take 6, 8, 12 days respectively. They work on alternate days in order A, B, C, A, B, C... Find total time.
Solution:
- Work in 3 days = 1/6 + 1/8 + 1/12 = 4/24 + 3/24 + 2/24 = 9/24 = 3/8
- After 2 cycles (6 days): work = 6/8 = 3/4, remaining = 1/4
- Day 7 (A): A's rate = 1/6 = 4/24, but 1/4 = 6/24 needed → A works full day, remaining after day 7 = 1/4 - 1/6 = 3/12 - 2/12 = 1/12
- Day 8 (B): B's rate = 1/8 = 3/24, remaining 1/12 = 2/24 → time needed = (2/24)/(3/24) = 2/3 day
- Total time = 7 + 2/3 = 7.67 days
Chapter 17 Practice Questions
Practice Question 1: A takes 10 days, B takes 15 days. How long together?
Answer: (10×15)/(10+15) = 150/25 = 6 days.
Practice Question 2: Pipe A fills in 5 hours, Pipe B empties in 10 hours. Time to fill if both open?
Answer: Net rate = 1/5 - 1/10 = 2/10 - 1/10 = 1/10. Time = 10 hours.
Practice Question 3: A is thrice as efficient as B. B takes 30 days alone. Find time if A and B work together.
Answer: A's time = 30/3 = 10 days. Together = (10×30)/(10+30) = 300/40 = 7.5 days.
Chapter 17 Summary
What are the key takeaways from Chapter 17?

Chapter 19 FAQs
What symbols should I use for drawing family trees?
Using standard symbols helps solve blood relations quickly:
Standard symbols:
- Male: □ (square) or + (plus sign) or M
- Female: ○ (circle) or – (minus sign) or F
- Marriage: = or – (horizontal line connecting two people)
- Parent-child: | (vertical line from parent to child)
- Siblings: — (horizontal line connecting children with bracket)
Generation tracking: Use G1, G2, G3 to mark generations (parents, children, grandchildren).
Tip: Start with definite relationships and build outward. If multiple possibilities exist, draw them separately.
What are the key blood relation terms for BBA entrances?
Understanding relationship terms is essential:
Immediate family:
- Father, Mother, Son, Daughter, Brother, Sister
- Husband, Wife
Extended family (same generation):
- Paternal Grandfather/Grandmother (father's parents)

- Brother-in-law: Spouse's brother, or sister's husband
- Sister-in-law: Spouse's sister, or brother's wife
How do I solve complex family tree puzzles?
Complex puzzles involve multiple generations and relationships. Use a systematic approach.
Step-by-step method:
- Step 1: Read all statements and list all persons mentioned.
- Step 2: Identify the root person (usually the one about whom question is asked).
- Step 3: Draw definite relationships first (e.g., "A is the father of B").
- Step 4: Use generations to place people at correct levels.
- Step 5: Resolve ambiguous relationships by considering possibilities.
- Step 6: Verify that all statements are satisfied.
What are coded blood relations problems?
Coded blood relations use symbols to represent relationships instead of words.
Example code patterns:
- A + B = A is the father of B
- A – B = A is the wife of B
- A × B = A is the brother of B
- A ÷ B = A is the mother of B
- A = B = A and B are siblings
Method: Decode the symbols into relationships, then draw family tree.
Example: If A + B means A is father of B, and B × C means B is brother of C, then A is father of C as well.
Mini Case Study: Complex Family Tree
Question: A is the father of B. C is the mother of D. D is the sister of B. How is A related to C?
Solution:
- A is father of B → B is child of A
- C is mother of D → D is child of C
- D is sister of B → B and D are siblings (same parents)
- Therefore A and C are parents (husband and wife)
- Answer: A is husband of C
Mini Case Study: Coded Blood Relations
Question: If P + Q means P is son of Q, P – Q means P is wife of Q, P × Q means P is brother of Q. Then find relation between A and C if A + B, B – C.
Solution:
- A + B: A is son of B
- B – C: B is wife of C
- So C is husband of B, and A is son of B
- Therefore C is father of A
- Answer: C is father of A
Chapter 19 Practice Questions
Practice Question 1: A is the mother of B. C is the brother of A. How is C related to B?

Chapter 20: Advanced Seating Arrangements (Circular, Square, Double Row)
Estimated Reading Time: 30 minutes
Chapter 20 FAQs
How do I solve circular seating arrangement problems?
Circular arrangement problems require arranging people around a circle. Direction of facing (center or outward) changes left/right interpretation.
Key concepts:
- If facing center: Left is clockwise direction, Right is anticlockwise
- If facing outward: Left is anticlockwise, Right is clockwise
- Fix one person's position to break symmetry (no absolute reference in circle)
Method:
- Step 1: Draw a circle with positions numbered 1 to N.
- Step 2: Fix one person at position 1 (top) to break symmetry.
- Step 3: Place people based on definite clues ("A sits opposite B", "C sits second to left of D").
- Step 4: Consider both possibilities when direction is ambiguous.
- Step 5: Eliminate impossible arrangements as you go.
How do I solve square/rectangular arrangement problems?
Square or rectangular arrangements have people sitting at corners or along sides. Some may face center, some outward.
Key points:
- 4 corners (North-East, North-West, South-East, South-West)
- Sometimes 4 sides (North, South, East, West) – midpoints
- Facing direction matters for left/right interpretation
Method:
- Draw a square and label corners/sides.
- Place people using definite clues.
- Use left/right carefully based on facing direction.
- At corners, a person can see two sides.
How do I solve double row arrangement problems?
Double row arrangements have people sitting in two parallel rows, often facing each other or facing the same direction.
Key patterns:
- Facing each other (North-South): Row 1 faces North, Row 2 faces South. Left of person in Row 1 is opposite to left of person in Row 2.
- Facing same direction: Both rows face North. Left/right are same for both rows.
- Facing opposite directions: Each row faces opposite direction.
Method:
- Draw two parallel lines with positions numbered 1 to N.
- Mark facing direction with arrows.
- Place definite positions first, then relative positions.
- Use clues like "A sits directly opposite B" or "C sits two places to the left of D".
What are the common traps in seating arrangements?
Common traps to watch for:
- Left/right confusion: Always check facing direction before determining left/right.
- Immediate neighbor vs second neighbor: "A sits next to B" vs "A sits second to the left of B".
- Opposite vs adjacent: In circle, opposite means directly across.
- Fixed reference: If no fixed reference, multiple arrangements possible – question may have multiple correct answers.
Mini Case Study: Circular Arrangement
Question: Six friends A,B,C,D,E,F sit around a circle facing center. A sits second to left of B. C sits opposite A. D sits immediate right of C. E sits between A and D. Find positions.
Solution:
- Fix A at position 1.
- A sits second to left of B → moving 2 steps anticlockwise from B gives A. So B is 2 steps clockwise from A → B at position 3.
- C sits opposite A → C at position 4 (directly across).
- D sits immediate right of C → facing center, right is clockwise. So D at position 5.
- E sits between A and D → A(1), D(5) → between means positions 2,3,4? But C at 4, B at 3 → E must be at position 2.
- F at remaining position 6.
Chapter 20 Practice Questions
Practice Question 1: In a circular arrangement facing center, if A is immediate left of B, where is B relative to A?
Answer: Immediate right of A (since facing center, left is clockwise, so A's left = B means B is clockwise from A, so B's right is anticlockwise from B = A).
Practice Question 2: In a double row facing each other, if A sits opposite B, and C sits second to left of A, where is C relative to B?
Answer: Since rows face each other, left/right are opposite. C would be second to right of B (or can be determined by drawing).
Chapter 20 Summary
What are the key takeaways from Chapter 20?
Chapter 20 covered advanced seating arrangements:
- Circular arrangement: Fix one person, use left/right based on facing direction, opposite means directly across.
- Square arrangement: Corners and sides, facing direction determines left/right.
- Double row: Facing each other (left/right opposite), facing same direction (left/right same).
- Traps: Always check facing direction before determining left/right.
Keywords: circular arrangement, square arrangement, double row, facing center, facing outward, opposite, adjacent, left right confusion
Chapter 21: Advanced Coding-Decoding (Conditional, Mathematical)
Estimated Reading Time: 25 minutes
Chapter 21 FAQs
What are the types of coding-decoding problems?
Coding-decoding problems can be categorized into several types:
1. Letter shifting (constant pattern): Each letter shifted by same number (A→C, B→D, etc.)
2. Reverse pattern: A↔Z, B↔Y, C↔X (mirror image)
3. Conditional coding: Different rules for vowels and consonants, or based on position
4. Mathematical coding: Letters replaced by numbers (A=1, B=2) with arithmetic operations
5. Symbolic coding: Letters replaced by symbols (@, #, $, etc.)
How do I solve conditional coding problems?
Conditional coding applies different rules based on letter type (vowel/consonant) or position (odd/even).
Method:
- Identify the condition (e.g., "vowels are shifted by +2, consonants by -1")
- Apply the rule to each letter based on its type
- Watch for vowels: A, E, I, O, U (and sometimes Y)
Example: Code "CAT" with vowels +1, consonants -1.
- C (consonant) → B
- A (vowel) → B
- T (consonant) → S
- Code = BBS
How do I solve mathematical coding problems?
Mathematical coding assigns numbers to letters (A=1, B=2, ... Z=26) and applies operations.
Common patterns:
- Sum of positions: CAT = 3+1+20 = 24
- Product of positions: CAT = 3×1×20 = 60
- Position squared: A=1, B=4, C=9, etc.
- Position reversed: A=26, B=25, C=24, etc.
Example: If DOG = 4+15+7 = 26, then CAT = 3+1+20 = 24.
Reverse mathematical: Given code as number, find original word.
How do I solve symbolic coding problems?
Symbolic coding replaces letters with symbols or uses symbols to represent operations.
Method:
- Create a mapping table from given examples
- Identify pattern (e.g., each letter replaced by a specific symbol)
- Apply mapping to new word
Example: If STAR is coded as @#$%, then RAIN would be coded using same mapping (R→#, A→?, I→?, N→?).
What is the reverse coding-decoding approach?
Reverse coding-decoding requires finding the original word from the code.
Method:
- Identify the coding pattern from given examples
- Apply inverse operation to decode
- For letter shifting: subtract instead of add
- For mathematical: solve equation to find original numbers, then convert to letters
Mini Case Study: Conditional Coding
Question: In a code, vowels are increased by 2 positions, consonants are decreased by 1 position. Code "CARE".
Solution:
- C (consonant, 3) → 3-1=2 → B
- A (vowel, 1) → 1+2=3 → C
- R (consonant, 18) → 18-1=17 → Q
- E (vowel, 5) → 5+2=7 → G
- Code: BCQG

Chapter 22: Advanced Syllogisms (Multiple Statements, Venn Diagrams)
Estimated Reading Time: 25 minutes
Chapter 22 FAQs
What are the basic syllogism statements and their Venn diagrams?
Syllogisms use four types of statements. Venn diagrams help visualize relationships.
Statement types:
- Universal Positive (All A are B): Circle A completely inside Circle B.
- Universal Negative (No A are B): Circles A and B do not overlap.
- Particular Positive (Some A are B): Overlap area has at least one element (X in intersection).
- Particular Negative (Some A are not B): A has part outside B (X in A but outside B).
Venn diagram method:
- Draw overlapping circles for each category.
- Shade areas that are empty.
- Mark with X where at least one element exists.
- Conclusion must be true in ALL possible diagrams.
How do I solve syllogisms with multiple statements (3 or more)?
Multiple statements require combining them systematically.
Method:
- Step 1: Write all statements clearly.
- Step 2: Identify common terms to combine statements.
- Step 3: Use the chain rule: If All A are B and All B are C, then All A are C.
- Step 4: For each conclusion, check if it follows from the statements.
Important rules:
- All A are B + Some B are C → No definite conclusion (C could be outside A).
- Some A are B + All B are C → Some A are C (definite).
- No A are B + All B are C → No definite conclusion about A and C.
What are the complementary pairs and special cases?
Complementary pairs are two conclusions where one must be true.
Complementary pairs:
- "All A are B" and "Some A are not B" are complements (one must be true).
- "No A are B" and "Some A are B" are complements.
Special case: If "All A are B" and "No A are B" cannot both be true.
"Either-or" conclusions: If neither conclusion follows individually, but together they form a complementary pair, then "either-or" is valid.
What is the chain rule for syllogisms?
The chain rule allows combining multiple statements to derive new conclusions.
Valid chains:
- All A are B + All B are C = All A are C
- All A are B + No B are C = No A are C
- Some A are B + All B are C = Some A are C
- Some A are B + No B are C = Some A are not C
Invalid chains:
- Some A are B + Some B are C = No definite conclusion
- No A are B + Some B are C = No definite conclusion
Mini Case Study: Multiple Statements
Statements: All lawyers are graduates. Some graduates are not employed. No employed are poor.
Conclusion 1: Some lawyers are not poor.
Analysis:
- All lawyers are graduates (Lawyer circle inside Graduate)
- No employed are poor (Employed and Poor circles don't overlap)
- But lawyers could be outside employed or inside employed? No direct link between lawyers and employed.
- Conclusion NOT valid (lawyers could all be poor if they are not employed).
Chapter 22 Practice Questions
Practice Question 1: Statements: All pens are pencils. Some pencils are erasers. Conclusions: (I) Some pens are erasers. (II) No pens are erasers.
Answer: Neither conclusion follows individually, but they form a complementary pair (Some + No). Therefore "Either I or II" follows.
Practice Question 2: Statements: No cats are dogs. All dogs are animals. Conclusion: Some animals are not cats.
Answer: Valid. All dogs are animals and no cats are dogs → dogs are animals that are not cats → Some animals are not cats.
Practice Question 3: Statements: Some books are novels. All novels are stories. Conclusion: Some books are stories.
Answer: Valid. Some books are novels, all novels are stories → Some books are stories.
Chapter 22 Summary
What are the key takeaways from Chapter 22?
Chapter 22 covered advanced syllogisms:
- Four statement types: All A are B (universal positive), No A are B (universal negative), Some A are B (particular positive), Some A are not B (particular negative).
- Venn diagram method: Draw circles, shade empty areas, mark X for existence.
- Chain rule: Combine statements: All A are B + All B are C = All A are C.
- Complementary pairs: "All" and "Some not" are complements; "No" and "Some" are complements. If neither follows, "either-or" may be valid.
Keywords: syllogisms, Venn diagrams, universal positive, universal negative, particular positive, particular negative, complementary pairs, chain rule, either-or conclusion
Chapter 23: Logical Connectives (If-Then, Only If, Unless, Contrapositive)
Estimated Reading Time: 25 minutes
Chapter 23 FAQs
What is the meaning of "If A then B" in logical reasoning?
"If A then B" is a conditional statement meaning that whenever A is true, B must also be true. It does NOT mean that B always requires A.
Symbolic representation: A → B (A implies B)
Truth table:
- If A is true, B must be true (A → B holds)
- If A is false, B can be true or false (statement still holds)
- If B is false, A must be false (contrapositive)
Example: "If it rains (A), then the ground will be wet (B)."
- If it rains → ground wet (true)
- If ground not wet → it did not rain (contrapositive)
- If ground wet → it may or may not have rained (could be from sprinkler)
What is the difference between "If" and "Only If"?
"If" and "Only If" have opposite meanings in logical reasoning.
"If A then B" (A → B): A is sufficient for B. A guarantees B.
"A only if B" (A → B as well): B is necessary for A. A cannot happen without B.
Key distinction:
- "If A then B" = A → B (A is sufficient, B is necessary)
- "A only if B" = A → B (same meaning!)
- "Only if A then B" = B → A (B happens only when A happens)
Example:
- "You will pass if you study" = Study → Pass (studying guarantees passing)
- "You will pass only if you study" = Pass → Study (passing requires studying)
What does "Unless" mean in logical reasoning?
"Unless" is a conditional word that can be translated into "If not".
Translation rule: "A unless B" = "If not B then A" = A ∨ B (A or B)
Example: "You will fail unless you study" = "If you do not study, then you will fail" = "You study or you fail".
Alternative translation: "Unless B, A" = "If not B, then A" = "A or B"
What is the contrapositive and how is it used?
The contrapositive of a conditional statement is logically equivalent to the original statement.
Contrapositive of "If A then B": "If not B then not A"
Example: "If it rains, the ground is wet" → Contrapositive: "If the ground is not wet, it did not rain."
Why it's useful: The contrapositive is always true when the original is true. It helps solve logical deduction problems.
Important: The converse ("If B then A") and inverse ("If not A then not B") are NOT logically equivalent to the original.
What are "If and only if" (biconditional) statements?
"If and only if" (often abbreviated as "iff") means the statement works both ways.
Symbolic representation: A ↔ B (A if and only if B)
Meaning: A → B AND B → A (A and B are equivalent)
Truth conditions: A and B must have the same truth value (both true or both false).
Example: "You will pass if and only if you study" = Studying is both necessary and sufficient for passing.
Mini Case Study: Logical Connectives in CLAT-Style Questions
Question: Statement: "If the alarm rings, then the thief is caught." Which of the following is logically equivalent?
Options: (A) If the thief is caught, the alarm rings. (B) If the thief is not caught, the alarm did not ring. (C) The alarm rings or the thief is caught.
Solution:
- Original: Alarm → Caught (A → C)
- Contrapositive: Not Caught → Not Alarm (If thief not caught, alarm did not ring) → Option B is correct
- Option A is converse (not equivalent)
- Option C is "Alarm or Caught" which is equivalent to "If not Alarm then Caught" (different meaning)
Chapter 23 Practice Questions
Practice Question 1: Write the contrapositive of "If you work hard, you will succeed."
Answer: "If you do not succeed, then you did not work hard."
Practice Question 2: What is the logical equivalent of "You will be late unless you leave early"?
Answer: "If you do not leave early, then you will be late" OR "You leave early or you will be late."
Practice Question 3: "A only if B" means the same as which of these: (a) If A then B, (b) If B then A, (c) If not A then not B?
Answer: (a) If A then B (A → B).
Chapter 23 Summary
What are the key takeaways from Chapter 23?
Chapter 23 covered logical connectives:
- If A then B (A → B): A is sufficient for B. Contrapositive: If not B then not A.
- A only if B: Also means A → B (B is necessary for A).
- Only if A then B: Means B → A (different direction).
- Unless: "A unless B" = "If not B then A" = "A or B".
- If and only if (A ↔ B): Both directions – A and B are equivalent.
Keywords: logical connectives, if then, only if, unless, contrapositive, biconditional, sufficient condition, necessary condition
Chapter 24: Series Completion and Analogy (Advanced)
Estimated Reading Time: 25 minutes
Chapter 24 FAQs
What are the types of number series questions?
Number series questions test pattern recognition. Common patterns include:
Arithmetic progression: Constant difference (2, 5, 8, 11, 14... difference 3)
Geometric progression: Constant ratio (3, 6, 12, 24, 48... ratio 2)
Square/cube series: 1, 4, 9, 16, 25... (squares); 1, 8, 27, 64, 125... (cubes)
Prime number series: 2, 3, 5, 7, 11, 13, 17, 19...
Fibonacci series: Each term is sum of previous two (1, 1, 2, 3, 5, 8, 13...)
Mixed operations: Add, then multiply, then subtract pattern (alternating operations)
How do I solve advanced number series problems?
Advanced series may have multiple patterns or complex operations.
Method:
- Find difference between consecutive terms
- If differences are constant → arithmetic progression
- If differences follow a pattern (increasing/decreasing), examine second-level differences
- Check ratio between terms for geometric progression
- Check if terms relate to squares, cubes, primes, or factorials
Example: 5, 7, 11, 17, 25, ?
- Differences: +2, +4, +6, +8 → next difference +10
- Next term = 25 + 10 = 35
How do I solve alphabet series and letter series problems?
Alphabet series use position numbers (A=1, B=2, ... Z=26).
Common patterns:
- Position shift: A, C, E, G... (A=1, C=3, E=5, G=7 → +2 each time)
- Reverse alphabet: Z, Y, X, W... (Z=26, Y=25, X=24, W=23 → -1 each time)
- Vowel series: A, E, I, O, U (vowels in order)
- Consonant series: B, D, F, H... (consonants with pattern)
- Mixed letter-number series: A1, B2, C3, D4... (letter and number both increase)
How do I solve analogy problems?
Analogy problems ask to find the relationship between a pair and apply it to another.
Types of analogies:
- Word analogies: Doctor : Hospital :: Teacher : School (person and workplace)
- Number analogies: 4 : 16 :: 7 : 49 (square relationship)
- Letter analogies: ABC : DEF :: GHI : JKL (letter shift)
- Symbol analogies: + : addition :: × : multiplication (symbol and operation)
Method:
- Identify the relationship in the given pair
- Apply the same relationship to the second pair to find the missing term
What are common analogy relationships tested in BBA entrances?
Common relationships include:
- Cause and effect: Rain : Flood (cause produces effect)
- Part to whole: Finger : Hand (finger is part of hand)
- Tool and action: Pen : Write (pen is used to write)
- Worker and product: Poet : Poem (poet creates poem)
- Degree of intensity: Warm : Hot (escalating intensity)
- Antonyms/Synonyms: Happy : Joyful (synonyms), Hot : Cold (antonyms)
- Mathematical operations: 3 : 9 :: 5 : 25 (square relationship)
Mini Case Study: Series Completion
Question: Find the next term: 2, 6, 12, 20, 30, ?
Solution:
- Differences: 6-2=4, 12-6=6, 20-12=8, 30-20=10
- Differences increase by 2 each time: 4,6,8,10 → next difference = 12
- Next term = 30 + 12 = 42
- Pattern also: 1×2, 2×3, 3×4, 4×5, 5×6 → next 6×7=42

Chapter 25: Mixed Graphs (Bar + Line + Table)
Estimated Reading Time: 25 minutes
Chapter 25 FAQs
What are mixed graphs in Data Interpretation?
Mixed graphs combine two or more types of data representation (bar chart, line graph, pie chart, table) in one question set. BBA entrance exams frequently use mixed graphs to test comprehensive DI skills.
Common mixed graph combinations:
- Bar graph showing sales + Line graph showing profit percentage
- Table showing production + Pie chart showing distribution
- Bar graph for one year + Line graph for trend over multiple years
- Two bar graphs with different units (quantity and price)
How do I solve mixed graph problems?
Step-by-step method:
- Step 1: Identify what each graph represents (different units, different time periods, different categories).
- Step 2: Note that different graphs may have different scales or totals – never assume they are the same.
- Step 3: Understand the relationship between graphs (e.g., bar shows quantity, line shows percentage).
- Step 4: Extract required data from each graph separately.
- Step 5: Combine data to answer the question (e.g., calculate actual value from percentage and total).
What are common mixed graph question types?
Common question types in mixed graphs:
Type 1: Bar + Line (Sales + Profit %)
- Bar shows sales (₹ crores)
- Line shows profit percentage
- Question: Find profit amount for a year = Sales × (Profit%/100)
Type 2: Table + Pie Chart (Production + Distribution)
- Table shows total production by year
- Pie chart shows distribution across regions for a specific year
- Question: Find production in a specific region = Total × (Pie angle/360)
Type 3: Two Bar Graphs (Different Units)
- Bar graph A shows quantity (units)
- Bar graph B shows price (₹ per unit)
- Question: Find total revenue = Quantity × Price
What are common traps in mixed graph problems?
Common traps to watch for:
- Different scales: Bar graphs may have different y-axis scales – don't compare bar heights directly.
- Different units: One graph in lakhs, another in crores – convert to common unit.
- Different time periods: Bar may show quarterly data, line may show annual data – match periods carefully.
- Misreading the relationship: Line may show percentage of something else, not directly related to bar.
- Ignoring secondary axis: In combined graphs, left and right axes may have different units.
Mini Case Study: Bar + Line Mixed Graph
Data: Bar graph shows sales (in ₹ lakhs) for 5 years: 2019:40, 2020:45, 2021:50, 2022:55, 2023:60. Line graph shows profit percentage: 2019:10%, 2020:12%, 2021:15%, 2022:18%, 2023:20%.
Question: Which year had the highest profit?
Solution:
- Profit = Sales × (Profit%/100)
- 2019: 40 × 0.10 = 4 lakhs
- 2020: 45 × 0.12 = 5.4 lakhs
- 2021: 50 × 0.15 = 7.5 lakhs
- 2022: 55 × 0.18 = 9.9 lakhs
- 2023: 60 × 0.20 = 12 lakhs
- Answer: 2023 had highest profit (12 lakhs)
Chapter 25 Practice Questions
Practice Question 1: In a bar + line graph, bar shows sales (₹ crores) and line shows profit %. How do you find profit?
Answer: Profit = Sales × (Profit%/100).
Practice Question 2: If table shows total production and pie chart shows regional distribution, how do you find production in a region?
Answer: Regional production = Total × (Angle/360°) or Total × (Percentage/100).
Practice Question 3: What is the most common trap in mixed graph problems?
Answer: Assuming different graphs have the same scale or total – always check units and axes separately.
Chapter 25 Summary
What are the key takeaways from Chapter 25?
Chapter 25 covered mixed graphs in Data Interpretation:
- Mixed graphs: Combine bar, line, pie, table – each may have different units, scales, or totals.
- Bar + Line: Common for sales + profit% – profit = sales × profit%.
- Table + Pie: Table gives total, pie gives distribution – regional value = total × (angle/360).
- Two Bar Graphs: Different units (quantity and price) – revenue = quantity × price.
- Common traps: Different scales, different units, different time periods, ignoring secondary axes.

Chapter 26: Caselets with Missing Data
Estimated Reading Time: 25 minutes
Chapter 26 FAQs
What are caselets in Data Interpretation?
Caselets are paragraph-based DI where data is presented in text form, not in tables or graphs. Some values may be missing and need to be derived from relationships.
Key characteristics:
- Data is embedded in a paragraph or story format
- Multiple variables with relationships described in words
- Some numbers may be missing – need to form equations
- Often combine arithmetic, ratio, and percentage concepts
How do I solve caselets with missing data?
Step-by-step method:
- Step 1: Read the caselet carefully and note all given numbers and relationships.
- Step 2: Identify unknown variables – use letters (x, y, z) for missing values.
- Step 3: Form equations based on relationships described (ratios, percentages, totals).
- Step 4: Solve for missing values using given totals or ratios.
- Step 5: Use the found values to answer specific questions.
What are common caselet patterns in BBA entrances?
Common caselet patterns include:
Pattern 1: Ratio-based caselets
- "In a college, ratio of boys to girls is 3:2. Number of boys who play cricket is 40% of total boys..."
- Use ratio to express numbers in terms of a variable: Boys = 3x, Girls = 2x, Total = 5x
Pattern 2: Percentage-based caselets
- "In an office, 60% of employees are graduates. 30% of graduates are from IIM. Number of non-graduates is 200..."
- Use percentages to form equations: Let total = T. Graduates = 0.6T, IIM graduates = 0.6T × 0.3 = 0.18T
Pattern 3: Two-variable caselets
- "Total revenue from Product A and B is ₹50,000. Revenue from A is 20% more than B..."
- Form equations: A + B = 50000, A = 1.2B → Solve
What are the common traps in caselet problems?
Common traps to watch for:
- Misreading relationships: "A is 20% more than B" vs "A is 20% of B" are very different.
- Percentage base confusion: "40% of graduates" vs "40% of total employees" – base matters.
- Missing total: Sometimes total is not given and must be derived from partial information.
- Overlapping sets: When categories overlap (e.g., graduates who are also IIM), use set theory.
Mini Case Study: Caselet with Missing Data
Caselet: In a school, ratio of boys to girls is 4:3. Number of boys who play football is 25% of total boys. Number of girls who play football is 40% of total girls. Total students who play football is 440. Find total students.
Solution:
- Let total students = 7x (since ratio 4:3, boys=4x, girls=3x)
- Boys playing football = 25% of 4x = 0.25 × 4x = 1x
- Girls playing football = 40% of 3x = 0.4 × 3x = 1.2x
- Total football players = 1x + 1.2x = 2.2x = 440
- x = 440/2.2 = 200
- Total students = 7x = 7 × 200 = 1400
Chapter 26 Practice Questions
Practice Question 1: In a class, 60% are boys. 50% of boys and 40% of girls passed. Total passed is 260. Find total students.
Answer: Let total = T. Boys = 0.6T, Girls = 0.4T. Passed = 0.5×0.6T + 0.4×0.4T = 0.3T + 0.16T = 0.46T = 260 → T = 260/0.46 = 565.22 → not integer? Check: 0.46 × 565 = 259.9 ≈ 260. Total ≈ 565.
Practice Question 2: A and B together earn ₹50,000. A earns 25% more than B. Find A's earnings.
Answer: B = x, A = 1.25x, Total = 2.25x = 50000 → x = 50000/2.25 = 22222.22. A = 1.25 × 22222.22 = ₹27,777.78.
Chapter 26 Summary
What are the key takeaways from Chapter 26?
Chapter 26 covered caselets with missing data:
- Caselets: Paragraph-based DI – data is in text, not tables or graphs.
- Method: Identify variables, form equations, solve systematically.
- Common patterns: Ratio-based, percentage-based, two-variable caselets.

Chapter 27: Advanced Reading Comprehension (Abstract, Philosophical, Legal Passages)
Estimated Reading Time: 25 minutes
Chapter 27 FAQs
How do I approach abstract and philosophical passages?
Abstract and philosophical passages discuss concepts like leadership, ethics, decision-making, management philosophy, and human behavior.
Strategy:
- Don't get lost in complexity: Focus on the author's main argument, not every detail.
- Identify the thesis: What is the author trying to prove or disprove?
- Track transitions: Words like "however", "therefore", "nevertheless" signal shifts in argument.
- Look for examples: Abstract points are often followed by concrete illustrations.
- Summarize each paragraph: Write 3-5 words after each paragraph in your mind.
How do I handle legal passages in BBA entrances?
Legal passages may appear in BBA entrances, especially in IPMAT and SET. They include excerpts from judgments, legal articles, or commentary on business laws.
Key elements to identify:
- The legal issue: What question is the court or author addressing?
- The holding: What is the decision or conclusion?
- The reasoning: Why did the court reach that conclusion?
- Application to business: How does this affect companies, contracts, or commerce?
CLAT Tip for BBA aspirants: Legal passages often have dense language. Read the first and last sentence of each paragraph first to get the structure.
What are the question types in advanced RC passages?
Advanced RC passages test deeper understanding:
Question types:
- Main idea / Central theme: What is the passage primarily about? (not too broad, not too narrow)
- Author's tone / attitude: Positive, negative, neutral, critical, skeptical, supportive?
- Inference: What can be logically concluded from the passage? (must be 100% provable)
- Structure / Organization: How does the author build the argument?
- Purpose of a specific paragraph: Why did the author include this paragraph?
- Assumption: What unstated belief does the author hold?
- Strengthen / Weaken: What would make the argument stronger or weaker?
What are the speed reading techniques for advanced passages?
Speed is critical in BBA entrances. Use these techniques:
Skimming:
- Read first sentence of each paragraph (often contains main idea)
- Read last sentence of each paragraph (often contains conclusion or transition)
- Look for transition words: however, therefore, nevertheless, for example, in contrast
- Do NOT read every word in first pass
Scanning:
- Read the question first, then scan passage for keywords
- For vocabulary questions, find the word and read surrounding sentences
- For detail questions, locate the specific sentence or paragraph
Mini Case Study: Abstract Passage Approach
Passage Excerpt: "Leadership is not merely about authority, but about influence. While formal positions grant power, true leadership emerges when individuals inspire others to achieve common goals. However, the modern workplace has seen a shift from hierarchical to collaborative leadership models."
Main idea: True leadership is about influence, not just formal authority, and is shifting toward collaboration.
Author's tone: Analytical and informative.
Inference: A person without a formal title can still be a leader if they inspire others.
Chapter 27 Practice Questions
Practice Question 1: How do you find the main idea of an abstract passage?
Answer: Read first and last sentences of each paragraph, then identify the common thread – not too broad, not too narrow.
Practice Question 2: What are the 4 speed reading techniques for RC?
Answer: (1) Read first sentence of each paragraph, (2) Read last sentence of each paragraph, (3) Look for transition words, (4) Read question first then scan for keywords.
Practice Question 3: How can you identify the author's tone?
Answer: Look for positive/negative words, qualifiers, and the overall attitude toward the subject – critical, supportive, neutral, skeptical, etc.

Chapter 28: Para-jumbles with 6-8 Sentences
Estimated Reading Time: 25 minutes
Chapter 28 FAQs
What are para-jumbles and why are they important for BBA entrances?
Para-jumbles (sentence rearrangement) test your ability to arrange jumbled sentences into a coherent, logical paragraph. They are important because:
- They appear in SET, NPAT, DU JAT, and IPMAT
- They test logical flow, coherence, and language skills
- Advanced para-jumbles have 6-8 sentences (harder than 4-5 sentence ones)
What is the step-by-step method for solving para-jumbles?
Method for 6-8 sentence para-jumbles:
- Step 1: Identify the opening sentence – introduces the topic, no pronouns referring back, no connectors like "however" or "therefore".
- Step 2: Identify the closing sentence – concludes the idea, no further development, often has conclusive words like "thus", "hence", "therefore".
- Step 3: Look for logical connectors – however (contrast), therefore (conclusion), for example (illustration), moreover (addition).
- Step 4: Look for pronoun references – "he", "she", "it", "they", "this", "these" – must follow the noun they refer to.
- Step 5: Look for chronological or cause-effect sequences.
- Step 6: Form pairs of sentences that naturally go together, then build the sequence.
What are the common para-jumble connectors?
Connectors help identify sentence order:
Contrast connectors: however, nevertheless, on the other hand, conversely, although, but, yet – these follow a sentence with an opposite idea.
Continuation connectors: moreover, furthermore, in addition, similarly, likewise, also – these continue the same idea.
Cause-effect connectors: therefore, thus, hence, consequently, as a result, so – these follow a sentence stating a cause.
Example connectors: for example, for instance, such as, to illustrate – these follow a general statement.
Sequence connectors: first, second, finally, subsequently, then, next – indicate chronological order.
What are the common traps in para-jumbles?
Common traps to watch for:
- Starting with a connector: A sentence beginning with "However" or "Therefore" cannot be the opening sentence.
- Pronoun without antecedent: A sentence with "He", "She", "It", "They" must have a previous sentence introducing that noun.
- Misidentifying the opening: The opening sentence should introduce the topic without assuming prior knowledge.
- Forcing a sequence: Sometimes multiple arrangements are possible – look for the most logical flow.
Mini Case Study: Para-jumble with 6 Sentences
Jumbled sentences:
- However, this approach has significant limitations.
- Many management theorists advocate for a data-driven decision-making process.
- They argue that intuition and experience are unreliable guides.
- Therefore, a balanced approach combining data and intuition may be more effective.
- Data can sometimes miss important contextual factors.
- Intuition, on the other hand, can capture subtle nuances.
Correct order: 2, 3, 1, 5, 6, 4
Explanation: Sentence 2 introduces the topic. Sentence 3 explains what theorists argue. Sentence 1 introduces contrast ("However"). Sentence 5 explains one limitation of data. Sentence 6 contrasts with intuition. Sentence 4 gives conclusion ("Therefore").
Chapter 28 Practice Questions
Practice Question 1: Why can't a sentence starting with "However" be the opening sentence?
Answer: Because "However" indicates contrast with a previous idea – it requires a preceding sentence to contrast with.
Practice Question 2: What is the first step in solving a para-jumble?
Answer: Identify the opening sentence – it introduces the topic without pronouns or connectors referring back.
Practice Question 3: What does a sentence starting with "For example" indicate?
Answer: It indicates that the previous sentence made a general statement, and this sentence provides an illustration.
Chapter 28 Summary
What are the key takeaways from Chapter 28?
Chapter 28 covered para-jumbles with 6-8 sentences:
- Step-by-step method: Identify opening → identify closing → look for connectors → look for pronouns → look for sequences → form pairs.

Mini Case Study: Sentence Correction Practice
Question: Identify the error in: "The committee members, along with the chairman, have decided to postpone the meeting until next week."
Analysis: The subject is "committee members" (plural), so "have decided" is correct. The phrase "along with the chairman" does not change the plural subject. This sentence is actually correct.
Question: "Neither the manager nor his assistants was present at the meeting."
Analysis: With "neither...nor", the verb agrees with the nearest subject. "Assistants" is plural, so verb should be "were". Correct: "Neither the manager nor his assistants were present."
Chapter 29 Practice Questions
Practice Question 1: Correct the sentence: "The data shows that the company are performing well."
Answer: "The data shows that the company is performing well." (company is singular)

Chapter 30: Critical Reasoning for BBA (Assumptions, Strengthen, Weaken, Inference)
Estimated Reading Time: 30 minutes
Chapter 30 FAQs
What is critical reasoning and how is it tested in BBA entrances?
Critical Reasoning tests your ability to analyze arguments, identify logical flaws, and draw conclusions. It appears in IPMAT, SET, NPAT, and DU JAT.
Common question types:
- Assumption: What unstated belief must be true for the argument to hold?
- Strengthen: What additional evidence would make the argument stronger?
- Weaken: What additional evidence would make the argument weaker?
- Inference: What must be true based only on the given information?
- Conclusion: What is the main point of the argument?
- Flaw: What is the logical error in the reasoning?
How do I identify and test assumptions?
An assumption is an unstated belief that connects the evidence to the conclusion.
Method – The Negation Test:
- Step 1: Identify the conclusion and evidence.
- Step 2: For each answer option, negate it (assume the opposite is true).
- Step 3: If the negated statement destroys the argument, it is a necessary assumption.
Example: "Coffee drinkers score higher on tests. Therefore, coffee improves test scores."
- Assumption: Coffee causes higher scores (not just correlation).
- Negation: Coffee does NOT cause higher scores → argument collapses.
How do I strengthen or weaken an argument?
Strengthen and weaken questions ask you to find evidence that supports or undermines the argument.
To strengthen an argument:
- Provide new evidence that supports the connection between evidence and conclusion
- Rule out alternative explanations
- Show the sample is representative
- Show the cause leads to the effect
To weaken an argument:
- Provide an alternative cause for the observed effect
- Show the sample is biased or unrepresentative
- Show the cause does not always lead to the effect
- Identify a flaw in the reasoning
Example: "New traffic fines reduced accidents by 30%. Therefore, higher fines work."
- Strengthen: "No other traffic safety measures were introduced during this period."
- Weaken: "The same period also saw increased police patrols and road repairs."
How do I draw inferences and conclusions?
Inferences and conclusions must be 100% provable from the given information.
Rules for inference questions:
- Correct inferences are 100% provable from the passage
- If an answer could be false, it is NOT a valid inference
- Do not bring outside knowledge
- Avoid options that are "probably true" or "could be true"
Example passage: "All CLAT aspirants practice mocks. Rohan is a CLAT aspirant."
- Valid inference: "Rohan practices mocks." (100% provable)
- Invalid inference: "Rohan will get into an NLU." (not provable)
What are common logical flaws in arguments?
Common flaws tested in BBA entrances:
- Correlation vs Causation: Assuming that because two things occur together, one causes the other.
- Hasty Generalization: Drawing a conclusion from a small or unrepresentative sample.
- False Dilemma: Presenting only two options when more exist.
- Ad Hominem: Attacking the person instead of the argument.
- Circular Reasoning: Using the conclusion as evidence for itself.
- Appeal to Authority: Claiming something is true because an authority says so (without evidence).
- Post Hoc Ergo Propter Hoc: Assuming A caused B just because A happened before B.
Mini Case Study: Critical Reasoning Practice
Argument: "A study found that law students who exercise daily have lower stress. Therefore, law schools should mandate daily exercise for all students."
Assumption: Exercise causes lower stress (not just correlation) AND mandatory exercise will not cause other problems.
Weaken: "Students who exercise daily also have better time management skills, which may reduce stress independently."
Strengthen: "A controlled study found that students randomly assigned to exercise had significantly lower stress than those who did not."
Chapter 30 Practice Questions
Practice Question 1: What is the negation test for assumptions?
Answer: Negate the assumption – if the negated statement makes the argument collapse, it was a necessary assumption.
Practice Question 2: How do you weaken a causal argument?
Answer: Provide an alternative cause, show the cause doesn't always lead to the effect, or show correlation without causation.
Practice Question 3: What is the difference between correlation and causation?
Answer: Correlation means two things occur together. Causation means one directly causes the other. Correlation does not imply causation.
Chapter 30 Summary
What are the key takeaways from Chapter 30?
Chapter 30 covered critical reasoning for BBA:
- Assumptions: Unstated beliefs – use negation test to identify necessary assumptions.
- Strengthen: Support the connection between evidence and conclusion; rule out alternatives.
- Weaken: Attack the connection; provide alternative causes; identify flaws.

How do I create a personalized time allocation plan?
Based on your mock test analysis from Chapter 10 and Chapter 37, create a personalized plan:
Step-by-step:
- Step 1: Review your accuracy and speed for each section from last 5 mocks.
- Step 2: Identify your strongest section – allocate 5-10% less time than average (you solve faster).
- Step 3: Identify your weakest section – allocate 10-15% more time than average.
- Step 4: Create a section order that starts with your strongest to build confidence.
- Step 5: Practice this allocation in every mock from now on.
Example personalized plan for IPMAT (120 min):
- Verbal (strongest): 35 minutes (save 5 minutes)
- Quant MCQ (medium): 40 minutes (standard)
- Quant SA (weakest): 45 minutes (extra 5 minutes)
What are the common time management mistakes to avoid?
Common mistakes that waste time:
- Perfectionism: Spending 3-4 minutes on a single question – learn to skip
- Re-reading passages: Read once, mark key points, don't re-read
- Over-calculating: Use approximation when options are far apart
- Second-guessing: Changing correct answers – first instinct is often right
- Poor section order: Starting with weakest section reduces confidence and time
- No buffer time: Always keep 5 minutes for review and bubbling
Mini Case Study: Time Management in Action

Chapter 37: Mock Test Analysis Framework (Error Categorization)
Estimated Reading Time: 25 minutes
Chapter 37 FAQs
What is a section-wise accuracy tracking sheet for Phase 2?
A section-wise accuracy tracking sheet helps you monitor your performance across all BBA entrance exam sections over multiple mock tests.
Sample tracking sheet format:
- Mock Test No.: 1, 2, 3, etc.
- Quantitative Aptitude: Attempted / Correct / Accuracy % / Time taken
- Logical Reasoning: Attempted / Correct / Accuracy % / Time taken
- Data Interpretation: Attempted / Correct / Accuracy % / Time taken
- Verbal Ability: Attempted / Correct / Accuracy % / Time taken
- Reading Comprehension: Attempted / Correct / Accuracy % / Time taken
- Business Awareness: Attempted / Correct / Accuracy % / Time taken
- General Awareness: Attempted / Correct / Accuracy % / Time taken
- Total Score: Raw score / Rank (if available)
Tip: Track both attempted questions AND accuracy separately. Attempting more questions with low accuracy is worse than attempting fewer with high accuracy due to negative marking.
What are the 4 types of question-level error categorization for Phase 2?
Categorizing your errors helps identify weak areas and focus your revision. The 4 categories are:
1. Concept Error (C):
- You did not understand the mathematical concept, logical reasoning pattern, or verbal rule.
- Remedy: Revise that specific topic from your notes or textbook.
- Phase 2 Example: Misapplying successive percentage formula, misunderstanding logical connectives, or misidentifying assumption in critical reasoning.
2. Speed Error (S):
- You knew the answer but ran out of time before solving.
- Remedy: Practice timed drills and skip strategies. Use approximation and option checking.
- Phase 2 Example: Leaving caselet DI questions unanswered due to slow calculation.
3. Silly Error (X):
- You knew the concept but made a careless mistake (misread question, wrong calculation, misclicked option).
- Remedy: Slow down during reading, double-check calculations, use elimination method.
- Phase 2 Example: Reading "least" as "greatest" or misreading left/right in seating arrangements.
4. Trap Error (T):
- You fell for a common BBA entrance trap option designed to mislead.
- Remedy: Learn the trap patterns (absolute words, unit confusion, base confusion, correlation vs causation).
- Phase 2 Example: Choosing "all A are B" when only "some A are B" is true in syllogisms.
How do I create and maintain a time log for Phase 2?
A time log tracks how much time you spend on each section and each question. This is critical for improving speed.
Time log format:
- Section: Quantitative Aptitude
- Total questions: 30
- Time allocated: 30 minutes
- Actual time taken: 35 minutes (5 minutes over)
- Time per question: Average 70 seconds (target 60 seconds)
- Questions taking >75 seconds: Question 7 (90 sec), Question 12 (110 sec), Question 24 (85 sec)
Phase 2 focus areas for time log:
- Mixed graphs and caselets (often take longer than expected)
- Complex seating arrangements (circular, double row)
- Advanced para-jumbles (6-8 sentences)
- Critical reasoning passages
How do I identify weak areas and create an improvement plan for Phase 2?
Weak area identification is the most important part of mock analysis. Without it, you will repeat the same mistakes.
Step-by-step weak area identification:
- Step 1: After each mock, list all incorrect questions.
- Step 2: For each incorrect question, mark error type (C/S/X/T).
- Step 3: For concept errors, note the specific advanced topic (e.g., "Successive percentage", "Logical connectives - unless", "Mixed graphs", "Critical reasoning - assumption").
- Step 4: After 5 mocks, compile frequency of each topic error.
- Step 5: Prioritize topics with highest error frequency for revision.
Sample improvement plan (Phase 2):
- Week 1: Revise Successive Percentages and CI-SI Difference (3 hours + 50 practice questions)
- Week 2: Revise Circular Seating Arrangements and Logical Connectives (2 hours + 40 questions)
- Week 3: Practice Mixed Graphs and Caselets (2 hours daily)
- Week 4: Work on Critical Reasoning (assumptions, strengthen/weaken) – 1 hour daily
What is the advanced mock analysis checklist for Phase 2?
After each mock test, complete this checklist:
- ☐ Calculate section-wise accuracy (%)
- ☐ Calculate time taken per section (compare to target)
- ☐ List all incorrect questions
- ☐ Categorize each error (C/S/X/T)
- ☐ For concept errors, note the specific topic
- ☐ Identify questions that took >90 seconds
- ☐ Review 5 randomly selected correct questions (confirm method was efficient)
- ☐ Write down 3 key learnings from this mock
- ☐ Plan revision for top 2 weak topics before next mock

Mini Case Study: 30-Day Revision Plan Example
Student Profile (Phase 2): Weak in Quant (especially Mixed Graphs and CI-SI Difference), moderate in LR, strong in Verbal.
Days 30-21: Focus on Mixed Graphs (2 hours daily) and CI-SI Difference (1 hour daily). Sectional tests on Quant only.
Days 20-11: Full mocks daily at 9 AM (exam time). Analyze each mock thoroughly. Quant accuracy improves from 65% to 75%.
Days 10-5: 3 mocks (every 2 days). Focus on timing and accuracy. Quant accuracy reaches 78%.
Days 5-2: Revise formula sheet, error log, business terminology. Light practice only.
Day 1: No study – prepare documents, visit center, relax.
Exam Day: Start with Verbal (strongest), then Quant, then LR. Uses 3-Round Method. Scores 10% higher than Phase 1 mocks.
