🧮 Aptitude Questions (15 with Solutions)

Question 1: Numbers

Find the unit digit of 4^102 × 9^51.

Solution: Unit digit of powers of 4 follows cycle: 4, 6, 4, 6...

  • Even power → Unit digit = 6
  • Odd power → Unit digit = 4

For 4^102: 102 is even, so unit digit = 6

Unit digit of powers of 9 follows cycle: 9, 1, 9, 1...

  • Even power → Unit digit = 1
  • Odd power → Unit digit = 9

For 9^51: 51 is odd, so unit digit = 9

Unit digit of product = 6 × 9 = 54 → Unit digit = 4

Question 2: Percentage

A number is increased by 20% and then decreased by 20%. What is the net change?

Solution: Shortcut formula: Net change = a + b + (ab/100) Where a = +20%, b = -20%

Net change = 20 - 20 + (20 × -20)/100 = 0 - 4 = -4% (decrease)

Question 3: Profit & Loss

A shopkeeper marks goods 40% above cost price and gives 25% discount. Find profit%.

Solution: Let CP = ₹100 Marked Price = 100 + 40% = ₹140 Selling Price = 140 - 25% of 140 = 140 - 35 = ₹105

Profit = 105 - 100 = ₹5 Profit% = 5%

Question 4: Time & Work

A can complete work in 12 days, B in 18 days. They work together for 4 days, then A leaves. How long will B take to complete remaining work?

Solution: A's 1 day work = 1/12 B's 1 day work = 1/18 Together in 4 days = 4 × (1/12 + 1/18) = 4 × (5/36) = 20/36 = 5/9

Remaining work = 1 - 5/9 = 4/9

Time for B to complete 4/9 work: = (4/9) ÷ (1/18) = (4/9) × 18 = 8 days

Question 5: Speed & Distance

A train 150m long crosses a platform 200m long in 35 seconds. Find speed in km/h.

Solution: Total distance = 150 + 200 = 350m Time = 35 seconds

Speed = 350/35 = 10 m/s Convert to km/h: 10 × 18/5 = 36 km/h

Question 6: Ratio & Proportion

If A:B = 3:4 and B:C = 5:6, find A:C.

Solution: A:B:C = 3×5 : 4×5 : 4×6 = 15:20:24

A:C = 15:24 = 5:8

Question 7: Averages

Average of 11 numbers is 50. Average of first 6 is 45, average of last 6 is 55. Find the 6th number.

Solution: Sum of 11 numbers = 11 × 50 = 550 Sum of first 6 = 6 × 45 = 270 Sum of last 6 = 6 × 55 = 330

6th number = (270 + 330) - 550 = 50

Question 8: Simple Interest

At what rate will ₹6000 amount to ₹8100 in 7 years at simple interest?

Solution: SI = 8100 - 6000 = ₹2100 Rate = (SI × 100)/(P × T) = (2100 × 100)/(6000 × 7) = 210000/42000 = 5%

Question 9: Compound Interest

The compound interest on a sum for 2 years at 10% per annum is ₹840. Find the sum.

Solution: CI = P[(1 + r/100)^n - 1] 840 = P[(1.1)^2 - 1] = P[1.21 - 1] = 0.21P

P = 840/0.21 = ₹4000

Question 10: Logical Reasoning - Series

Find the next term: 2, 6, 12, 20, 30, ?

Solution: Pattern: 1×2, 2×3, 3×4, 4×5, 5×6, ... Next term = 6 × 7 = 42

Question 11: Coding-Decoding

If COMPUTER is coded as RFUVQNPC, how is MEDICINE coded?

Solution: Pattern: Each letter shifted by +1, -1 alternately C→D(+1), O→N(-1), M→N(+1), P→O(-1)...

MEDICINE: M→N, E→D, D→E, I→H, C→D, I→H, N→O, E→D = NDEHDHOD

Question 12: Blood Relations

Pointing to a man, a woman said, "His mother is the only daughter of my mother." How is the woman related to the man?

Solution:

  • Only daughter of woman's mother = Woman herself
  • So the man's mother is the woman
  • Woman is the mother of the man

Question 13: Direction Sense

A man walks 5km North, turns right and walks 3km, turns right and walks 5km. How far is he from start?

Solution: Visualizing: North 5km, East 3km, South 5km Final position: 3km East of start Distance = 3 km

Question 14: Pipes & Cisterns

Pipe A fills tank in 6 hours, Pipe B empties in 8 hours. If both open, when will tank fill?

Solution: Net filling in 1 hour = 1/6 - 1/8 = (4-3)/24 = 1/24 Time to fill = 24 hours

Question 15: Calendar

What day of the week was January 1, 2024?

Solution: Using odd days method: 2000 years = 0 odd days 23 years (2001-2023): 17 normal + 6 leap years = 17×1 + 6×2 = 29 odd days = 1 odd day Jan 1, 2024 = 1 odd day
