🧮 Aptitude Questions with Solutions (15 Questions)

Question 1: Number Series

Find the next number: 3, 12, 27, 48, 75, ?

Solution: Pattern: 3×1², 3×2², 3×3², 3×4², 3×5²...

  • 3×1 = 3
  • 3×4 = 12
  • 3×9 = 27
  • 3×16 = 48
  • 3×25 = 75
  • 3×36 = 108

Question 2: Profit & Loss

By selling 33 meters of cloth, a shopkeeper gains the cost price of 11 meters. Find gain percentage.

Solution: Gain = CP of 11m SP of 33m = CP of 33m + CP of 11m = CP of 44m

Gain% = (11/33) × 100 = 33.33%

Question 3: Time & Work

A can do a work in 15 days, B in 20 days. They work together for 5 days, then C completes the remaining work in 5 days. How long would C take alone?

Solution: (A+B)'s 1 day work = 1/15 + 1/20 = 7/60 Work done in 5 days = 35/60 = 7/12 Remaining work = 5/12

C does 5/12 work in 5 days C's 1 day work = (5/12)/5 = 1/12

C alone = 12 days

Question 4: Speed & Distance

A car travels first 160 km at 64 km/hr and next 160 km at 80 km/hr. Find average speed.

Solution: Time 1 = 160/64 = 2.5 hours Time 2 = 160/80 = 2 hours Total distance = 320 km Total time = 4.5 hours

Average speed = 320/4.5 = 71.11 km/hr

Question 5: Ratio & Proportion

The ratio of incomes of A and B is 5:4 and expenditures is 3:2. If each saves ₹1600, find A's income.

Solution: Let incomes be 5x and 4x Let expenditures be 3y and 2y

5x - 3y = 1600 4x - 2y = 1600

From 2nd: 2x - y = 800 → y = 2x - 800 Substituting: 5x - 3(2x-800) = 1600 5x - 6x + 2400 = 1600 x = 800

A's income = 5 × 800 = ₹4000

Question 6: Compound Interest

The difference between compound interest and simple interest on ₹5000 for 2 years at 4% per annum is:

Solution: Difference = P(r/100)² = 5000 × (4/100)² = 5000 × 0.0016 = ₹8

Question 7: Probability

Two cards are drawn from a pack of 52 cards. Find probability that both are kings.

Solution: P(1st King) = 4/52 = 1/13 P(2nd King) = 3/51 = 1/17

P(Both Kings) = (1/13) × (1/17) = 1/221

Question 8: Permutations

In how many ways can 6 people be seated around a circular table?

Solution: Circular permutations = (n-1)! = (6-1)! = 5! = 120

Question 9: Mixtures

A container has 40L milk. 4L is taken out and replaced with water. This is repeated twice. How much milk remains?

Solution: Using formula: Final milk = Initial × (1 - x/n)^n Where x = replaced amount, n = number of times

Milk remaining = 40 × (1 - 4/40)³ = 40 × (9/10)³ = 40 × 0.729 = 29.16 liters

Question 10: Calendar

What was the day on 15th August 1947?

Solution: Using odd days method: 1600 years = 0 odd days 300 years = 1 odd day 46 years = 35 normal + 11 leap = 35 + 22 = 57 = 1 odd day Jan 1 to Aug 15, 1947 = 31+28+31+30+31+30+31+15 = 227 days = 3 odd days

Total = 0+1+1+3 = 5 odd days = Friday

Question 11: Percentage

If the price of sugar increases by 25%, by what percentage should consumption decrease to maintain the same expenditure?

Solution: % decrease = (25/125) × 100 = 20%

Question 12: Boats & Streams

A boat covers 24 km upstream in 6 hours and 20 km downstream in 4 hours. Find the speed of the boat in still water.

Solution: Upstream speed = 24/6 = 4 km/hr Downstream speed = 20/4 = 5 km/hr

Boat speed = (5+4)/2 = 4.5 km/hr

Question 13: HCF LCM

The HCF of two numbers is 12 and their product is 2160. Find the LCM.

Solution: HCF × LCM = Product of numbers 12 × LCM = 2160 LCM = 2160/12 = 180

Question 14: Averages

The average of 5 consecutive odd numbers is 25. Find the largest number.

Solution: Let numbers be x-4, x-2, x, x+2, x+4 Average = x = 25

Largest = x + 4 = 29

Question 15: Data Interpretation

A pie chart shows company expenses: Salaries 40%, Marketing 25%, Operations 20%, R&D 15%. If total budget is ₹20 lakhs, find Operations budget.

Solution: Operations = 20% of 20,00,000 = 0.20 × 20,00,000 = ₹4,00,000

        if complement in seen:
            return [seen[complement], i]
        seen[num] = i
