🧮 Aptitude Questions (15 Questions with Solutions)

Question 1: Percentages

A number is first increased by 10% and then decreased by 10%. What is the net change?

Options:

(a) 1% increase
(b) 1% decrease
(c) No change
(d) 2% decrease

Solution: Let original = 100 After 10% increase: 110 After 10% decrease: 110 × 0.90 = 99

Net change = 100 - 99 = 1% decrease

Formula: Net % = a + b + ab/100 = 10 - 10 + (10×-10)/100 = -1%

Question 2: Time and Work

A and B can complete a work in 12 days. B and C can complete it in 15 days. C and A can complete it in 20 days. How long will A, B, and C take together?

Options:

(a) 8 days
(b) 9 days
(c) 10 days
(d) 12 days

Solution: A + B = 1/12 per day B + C = 1/15 per day C + A = 1/20 per day

Adding all three: 2(A + B + C) = 1/12 + 1/15 + 1/20 = (5 + 4 + 3)/60 = 12/60 = 1/5

A + B + C = 1/10 per day

Time taken together = 10 days

Question 3: Number Series

Find the next term: 0, 1, 1, 2, 3, 5, 8, 13, ?

Options:

(a) 19
(b) 20
(c) 21
(d) 22

Solution: Fibonacci series: Each number is the sum of two preceding ones. 0 + 1 = 1 1 + 1 = 2 1 + 2 = 3 2 + 3 = 5 3 + 5 = 8 5 + 8 = 13 8 + 13 = 21

Question 4: Profit and Loss

By selling 36 oranges, a vendor loses the selling price of 4 oranges. What is his loss percentage?

Options:

(a) 10%
(b) 11.11%
(c) 12.5%
(d) 15%

Solution: Let SP of 1 orange = ₹1 SP of 36 oranges = ₹36 Loss = SP of 4 oranges = ₹4

CP = SP + Loss = 36 + 4 = ₹40

Loss % = (4/40) × 100 = 10%

Question 5: Probability

Two dice are thrown. What is the probability of getting a sum greater than 9?

Options:

(a) 1/6
(b) 1/9
(c) 1/12
(d) 5/18

Solution: Total outcomes = 36

Sum > 9 means sum = 10, 11, or 12

Sum = 10: (4,6), (5,5), (6,4) = 3 ways
Sum = 11: (5,6), (6,5) = 2 ways
Sum = 12: (6,6) = 1 way

Favorable = 6 Probability = 6/36 = 1/6

Question 6: Ratio and Proportion

The ratio of ages of A and B is 4:5. After 6 years, the ratio becomes 6:7. What is the present age of A?

Options:

(a) 12 years
(b) 18 years
(c) 24 years
(d) 30 years

Solution: Let present ages = 4x and 5x

(4x + 6)/(5x + 6) = 6/7

Cross multiply: 7(4x + 6) = 6(5x + 6) 28x + 42 = 30x + 36 42 - 36 = 30x - 28x 6 = 2x x = 3

A's present age = 4x = 12 years

Question 7: Simple Interest

A sum of money becomes 3 times itself in 8 years at simple interest. In how many years will it become 5 times itself?

Options:

(a) 12 years
(b) 14 years
(c) 16 years
(d) 20 years

Solution: Amount = 3P, so SI = 2P in 8 years

Rate = (SI × 100)/(P × T) = (2P × 100)/(P × 8) = 25%

For amount to become 5P: SI needed = 4P Time = (4P × 100)/(P × 25) = 16 years

Question 8: Data Interpretation

The table shows sales (in thousands) of a company:

Quarter	2023	2024
Q1	120	140
Q2	150	180
Q3	130	160
Q4	200	220

What is the percentage growth in total sales from 2023 to 2024?

Options:

(a) 15%
(b) 16.67%
(c) 18%
(d) 20%

Solution: Total 2023 = 120 + 150 + 130 + 200 = 600 Total 2024 = 140 + 180 + 160 + 220 = 700

Growth = (700 - 600)/600 × 100 = 100/600 × 100 = 16.67%

Question 9: Permutations

How many ways can the letters of the word 'LEADING' be arranged such that the vowels are always together?

Options:

(a) 480
(b) 576
(c) 720
(d) 840

Solution: Vowels: E, A, I (3) Consonants: L, D, N, G (4)

Treat vowels as one unit: 5 units total Arrangements = 5! × 3! = 120 × 6 = 720

Options:

(a) 70 km/hr
(b) 75 km/hr
(c) 80 km/hr
(d) 85 km/hr

Solution: Distance = 60 × 4 = 240 km Required speed = 240/3 = 80 km/hr

Question 11: Partnership

A and B start a business with ₹45,000 and ₹30,000 respectively. After 6 months, C joins with ₹60,000. If the total profit after one year is ₹18,000, what is C's share?

Options:

(a) ₹4,000
(b) ₹5,000
(c) ₹6,000
(d) ₹7,000

Solution: Investment periods:

A: 12 months × ₹45,000 = 5,40,000
B: 12 months × ₹30,000 = 3,60,000
C: 6 months × ₹60,000 = 3,60,000

Ratio A:B:C = 540:360:360 = 3:2:2

C's share = (2/7) × 18000 = ₹5,142

Given options, closest is (b) ₹5,000

Question 12: Calendar

What was the day on 15th August 1947 (Independence Day)?

Options:

(a) Wednesday
(b) Thursday
(c) Friday
(d) Saturday

Solution: Using odd day method:

1600 years: 0 odd days
300 years: 1 odd day
46 years: 35 ordinary + 11 leap = 35 + 22 = 57 = 1 odd day
Days till Aug 15, 1947: 31+28+31+30+31+30+31+15 = 227 = 3 odd days

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

Question 13: Boats and Streams

A boat covers 24 km upstream in 6 hours. If the speed of the stream is 2 km/hr, what is the speed of the boat in still water?

Options:

(a) 4 km/hr
(b) 5 km/hr
(c) 6 km/hr
(d) 8 km/hr

Solution: Upstream speed = 24/6 = 4 km/hr B - S = 4 B - 2 = 4 B = 6 km/hr

I. Some pens are pencils. II. Some pencils are pens.

Options:

(a) Only I
(b) Only II
(c) Both
(d) Neither

Solution: Using Venn diagrams:

Pens ⊂ Books
Pencils ∩ Books ≠ ∅

There is no definite overlap between Pens and Pencils. Neither conclusion necessarily follows.

If MOUSE is coded as PRXUH, how is KEYBOARD coded?

Options:

(a) NHBRDUG
(b) NHBAREUG
(c) NHBRDUF
(d) NIBRDUG

Solution: M → P (+3) O → R (+3) U → X (+3) S → U (+2) E → H (+3)

Pattern mostly +3, with S→U being +2 (possibly vowel/consonant difference)

Applying +3 to KEYBOARD: K → N E → H Y → B B → E O → R A → D R → U D → G

Result: NHB R DUG → (a) NHBRDUG
