Quantitative Aptitude Questions

Q1: Profit Percentage

A shopkeeper sells an item at 20% profit. If he had bought it at 10% less and sold it for ₹40 less, he would have gained 25%. Find the cost price.

Solution:

Let CP = ₹100
SP at 20% profit = ₹120
New CP (10% less) = ₹90
New SP = ₹120 - ₹40 = ₹80
Profit = (80-90)/90 × 100 = -11.11% (loss)

Using formula: CP = (Difference in SP × 100) / (Difference in profit %)
CP = (40 × 100) / (25 - 20) = ₹800

Answer: ₹800

Q2: Consumption Reduction

The price of a product is increased by 25%. By what percentage should the consumption be reduced so that the expenditure remains the same?

Solution:

Let original price = ₹100, consumption = 100 units
New price = ₹125
Original expenditure = 100 × 100 = ₹10,000
New consumption = 10,000 / 125 = 80 units
Reduction = (100 - 80) / 100 × 100 = 20%

Answer: 20%

Q3: Overall Profit/Loss

A man sells two articles for ₹4000 each, one at 20% profit and the other at 20% loss. Find his overall profit or loss percentage.

Solution:

For first article: CP₁ = 4000 / 1.20 = ₹3333.33
For second article: CP₂ = 4000 / 0.80 = ₹5000
Total CP = ₹8333.33
Total SP = ₹8000
Loss = (8333.33 - 8000) / 8333.33 × 100 = 4%

Answer: 4% loss

Q4: Successive Discounts

A shopkeeper offers two successive discounts of 20% and 15%. What is the effective discount percentage?

Solution:

Let MP = ₹100
After first discount: 100 - 20% = ₹80
After second discount: 80 - 15% = ₹68
Effective discount = (100 - 68) / 100 × 100 = 32%

Answer: 32%

Q5: Combined Work

A can complete a work in 12 days, B in 15 days. They work together for 4 days, then A leaves. In how many days will B complete the remaining work?

Solution:

A's 1 day work = 1/12
B's 1 day work = 1/15
Together in 1 day = 1/12 + 1/15 = 9/60 = 3/20
Work done in 4 days = 4 × 3/20 = 12/20 = 3/5
Remaining work = 1 - 3/5 = 2/5
B will complete in = (2/5) / (1/15) = 6 days

Answer: 6 days

Q6: Men Leaving

15 men can complete a work in 20 days. After 5 days, 5 men leave. How many more days will it take to complete the work?

Solution:

Total work = 15 × 20 = 300 man-days
Work done in 5 days = 15 × 5 = 75 man-days
Remaining work = 300 - 75 = 225 man-days
Remaining men = 15 - 5 = 10
Days required = 225 / 10 = 22.5 days

Answer: 22.5 days

Q7: Efficiency

A is twice as efficient as B. If A can complete a work in 10 days, how long will it take if both work together?

Solution:

A's efficiency = 2 units/day
B's efficiency = 1 unit/day
Total work = 2 × 10 = 20 units
Together efficiency = 2 + 1 = 3 units/day
Time = 20 / 3 = 6.67 days

Answer: 6.67 days

Q8: Train & Platform

A train crosses a platform in 30 seconds and a man standing on the platform in 18 seconds. If the speed of the train is 60 km/hr, find the length of the platform.

Solution:

Speed = 60 km/hr = 60 × 5/18 = 50/3 m/s
Length of train = 50/3 × 18 = 300 m

Let platform length = x m
(300 + x) / (50/3) = 30
300 + x = 500
x = 200 m

Answer: 200 m

Q9: Relative Speed

Two trains of lengths 200m and 300m are moving in opposite directions at speeds of 50 km/hr and 40 km/hr. Find the time taken to cross each other.

Solution:

Relative speed = 50 + 40 = 90 km/hr = 90 × 5/18 = 25 m/s
Total distance = 200 + 300 = 500 m
Time = 500 / 25 = 20 seconds

Answer: 20 seconds

Q10: Milk & Water

In a mixture of 60 liters, the ratio of milk and water is 2:1. How much water should be added to make the ratio 1:2?

Solution:

Current: Milk = 40L, Water = 20L
Let x liters water be added
40 / (20 + x) = 1/2
80 = 20 + x
x = 60 liters

Answer: 60 liters

Q11: Doubling Time

A sum of money doubles itself in 5 years at simple interest. In how many years will it become 4 times?

Solution:

If money doubles in 5 years, rate = 100/5 = 20% p.a.
To become 4 times, interest needed = 300%
Time = 300/20 = 15 years

Answer: 15 years

Q12: Compound Interest

Find the compound interest on ₹10,000 for 2 years at 10% per annum, compounded annually.

Solution:

Amount = P(1 + r/100)ⁿ = 10000(1.1)² = ₹12,100
CI = 12,100 - 10,000 = ₹2,100

Answer: ₹2,100

Q13: Sales Growth

The following table shows the sales of a company over 5 years. Find the average annual growth rate.

Year	Sales (in crores)
2020	100
2021	120
2022	150
2023	180
2024	200

Solution:

Average growth rate = [(120-100)/100 + (150-120)/120 + (180-150)/150 + (200-180)/180] / 4 × 100
= [20% + 25% + 20% + 11.11%] / 4 = 19.03%

Answer: 19.03%

Q14: Average Age

The average age of a class of 30 students is 20 years. If the teacher’s age is included, the average becomes 21 years. Find the teacher’s age.

Solution:

Total age of 30 students = 30 × 20 = 600
Total age including teacher = 31 × 21 = 651
Teacher's age = 651 - 600 = 51 years

Answer: 51 years

Q15: Ratio Problems

The ratio of boys to girls in a class is 3:2. If 5 more girls join, the ratio becomes 3:4. Find the initial number of students.

Solution:

Let boys = 3x, girls = 2x
After: 3x / (2x + 5) = 3/4
12x = 6x + 15
6x = 15
x = 2.5
Initial students = 3x + 2x = 5x = 12.5 (round to 13)

Answer: 13 students

Q16: LCM and HCF

Solution:

Let present ages be 3x and 5x
After 5 years: (3x + 5) / (5x + 5) = 4/6
6(3x + 5) = 4(5x + 5)
18x + 30 = 20x + 20
2x = 10
x = 5
A's age = 3x = 15 years

Answer: 15 years

Q21: Age Problems

The sum of ages of father and son is 50 years. Five years ago, the father was 5 times as old as the son. Find the present age of the son.

Solution:

Let son's age = x, father's age = 50 - x
5 years ago: (50 - x - 5) = 5(x - 5)
45 - x = 5x - 25
6x = 70
x = 11.67 ≈ 12 years

Answer: 12 years

Q22: Age Difference

A is twice as old as B. 10 years ago, A was 4 times as old as B. Find the present age of A.

10 years ago: (2x - 10) = 4(x - 10)
2x - 10 = 4x - 40
2x = 30
x = 15
A's age = 2x = 30 years

Answer: 30 years
