Quantitative Aptitude Questions with Solutions

Question 1: LCM and HCF

Problem: The LCM of two numbers is 495 and their HCF is 5. If the sum of the numbers is 100, find their difference.

Solution: Let the numbers be 5a and 5b (since HCF is 5)

LCM × HCF = Product of numbers 495 × 5 = 5a × 5b 2475 = 25ab ab = 99

Also: 5a + 5b = 100 a + b = 20

We have: a + b = 20 and ab = 99 a and b are roots of: x² - 20x + 99 = 0 (x - 9)(x - 11) = 0 So a = 9, b = 11 (or vice versa)

Numbers are: 5×9 = 45 and 5×11 = 55 Difference = 55 - 45 = 10


Question 2: Compound Interest

Problem: A sum of money doubles itself in 8 years at compound interest. In how many years will it become four times?

Solution: If money doubles in 8 years: P becomes 2P in 8 years

To become 4 times: 2P becomes 4P in another 8 years

Total time = 8 + 8 = 16 years

Shortcut: Doubling time is constant in CI. To become 4 times (2²), it takes 2 × doubling time = 16 years.


Question 3: Ratio and Proportion

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

Solution: Let present ages be 4x and 5x

After 6 years: (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

Present age of A = 4x = 4 × 3 = 12 years


Question 4: Time and Work

Problem: A, B, and C can complete a work in 10, 12, and 15 days respectively. If they work together, how many days will they take?

Solution: A's 1 day work = 1/10 B's 1 day work = 1/12 C's 1 day work = 1/15

(A + B + C)'s 1 day work = 1/10 + 1/12 + 1/15

LCM of 10, 12, 15 = 60 = 6/60 + 5/60 + 4/60 = 15/60 = 1/4

Days required = 4 days


Question 5: Mixture and Alligation

Problem: A mixture of 60 liters contains milk and water in the ratio 3:2. How much water must be added to make the ratio 1:1?

Solution: Milk in mixture = (3/5) × 60 = 36 liters Water in mixture = (2/5) × 60 = 24 liters

Let x liters of water be added. For ratio 1:1: 36/(24 + x) = 1/1 36 = 24 + x x = 12 liters


Question 6: Probability

Problem: Two dice are thrown simultaneously. Find the probability of getting a sum of 7.

Solution: Total outcomes = 6 × 6 = 36

Favorable outcomes for sum 7: (1,6), (2,5), (3,4), (4,3), (5,2), (6,1) Number of favorable outcomes = 6

Probability = 6/36 = 1/6


Question 7: Partnership

Problem: A, B, and C invest ₹50,000, ₹70,000, and ₹80,000 respectively. A is a working partner and gets 10% of the profit. The remaining profit is divided in the ratio of their investments. If the total profit is ₹72,000, find A's share.

Solution: A's working partner share = 10% of 72,000 = ₹7,200

Remaining profit = 72,000 - 7,200 = ₹64,800

Investment ratio: A:B:C = 50,000:70,000:80,000 = 5:7:8

A's share from investment = (5/20) × 64,800 = ₹16,200

Total share of A = 7,200 + 16,200 = ₹23,400


Question 8: Data Interpretation

Problem: Study the following table and answer:

YearProduction (in tons)
2021200
2022250
2023300
2024280

What is the average production?

Solution: Total production = 200 + 250 + 300 + 280 = 1030 tons Number of years = 4

Average = 1030/4 = 257.5 tons


Question 9: Surds and Indices

Problem: Simplify: (16)³/⁴

Solution: (16)³/⁴ = (2⁴)³/⁴ = 2^(4 × 3/4) = 2³ = 8


Question 10: Quadratic Equations

Problem: Find the roots of: x² - 7x + 12 = 0

Solution: x² - 7x + 12 = 0 x² - 4x - 3x + 12 = 0 x(x - 4) - 3(x - 4) = 0 (x - 4)(x - 3) = 0

Roots: x = 4 and x = 3


Question 11: Geometry

Problem: The diagonal of a square is 10√2 cm. Find its area.

Solution: In a square, diagonal = side × √2 So, side = 10√2/√2 = 10 cm

Area = side² = 10² = 100 cm²


Question 12: Trigonometry

Problem: If tan θ = 4/3, find sin θ.

Solution: tan θ = opposite/adjacent = 4/3

Using Pythagoras: hypotenuse = √(4² + 3²) = √(16 + 9) = √25 = 5

sin θ = opposite/hypotenuse = 4/5


Question 13: Calendar

Problem: What day of the week was January 26, 1950 (Republic Day)?

Solution: Using odd days method:

  • 1600 years: 0 odd days
  • 300 years: 1 odd day (5 odd days per 100 years)
  • 49 years: 37 ordinary + 12 leap = 49 + 12 = 61 odd days = 5 odd days
  • Days till Jan 26, 1950: 26 days = 5 odd days

Total odd days = 0 + 1 + 5 + 5 = 11 = 4 odd days

4 odd days = Thursday


Question 14: Number Series

Problem: Find the missing number: 1, 8, 27, 64, 125, ?

Solution: Pattern: 1 = 1³ 8 = 2³ 27 = 3³ 64 = 4³ 125 = 5³

Next = 6³ = 216


Question 15: Boats and Streams

Problem: A boat can travel 20 km downstream in 2 hours and 12 km upstream in 3 hours. Find the speed of the boat in still water.

Solution: Downstream speed = 20/2 = 10 km/hr Upstream speed = 12/3 = 4 km/hr

Speed of boat in still water = (Downstream + Upstream)/2 = (10 + 4)/2 = 7 km/hr


Reasoning Questions with Solutions

Question 1: Series Completion

Problem: Find the next term: AZ, CX, EV, GT, ?

Solution: Pattern: First letters: A(+2)→C(+2)→E(+2)→G(+2)→I Second letters: Z(-2)→X(-2)→V(-2)→T(-2)→R


Question 2: Coding-Decoding

Problem: In a code language, 'DRDO' is written as 'ESFR'. How is 'CEPTAM' written?

Solution: Pattern: Each letter is shifted by +1, +2, +3, +4... alternately

D(+1)→E, R(+2)→T, D(+3)→G... Wait, let me recheck.

D→E (+1) R→S (+1) D→E (+1) O→P (+1)

Actually simple +1 pattern: D→E, R→S, D→E, O→P

Applying to CEPTAM: C→D, E→F, P→Q, T→U, A→B, M→N


Question 3: Analogy

Problem: Scientist : Laboratory :: Soldier : ?

Solution: A scientist works in a laboratory. Similarly, a soldier works in a barrack/cantonment.


Question 4: Blood Relations

Problem: Pointing to a photograph, a man said, "She is the daughter of my wife's mother-in-law." How is the woman related to the man?

Solution:

  • Man's wife's mother-in-law = Man's mother
  • Daughter of man's mother = Man's sister

Question 5: Direction Sense

Problem: A person walks 5 km North, turns East and walks 3 km, then turns South and walks 5 km. How far is he from the starting point?

Solution:

  • Start (0,0), walk 5 km North → (0, 5)
  • Walk 3 km East → (3, 5)
  • Walk 5 km South → (3, 0)

Distance from origin = 3 km (East)


Question 6: Syllogism

Problem: Statements:

  1. All researchers are scientists.
  2. Some scientists are engineers.

Conclusions: I. Some researchers are engineers. II. Some engineers are scientists.

Solution: Conclusion I does not necessarily follow (researchers might not be among those scientists who are engineers). Conclusion II follows (since some scientists are engineers, some engineers are definitely scientists).


Question 7: Classification

Problem: Find the odd one out: Missile, Tank, Radar, Rifle

Solution: Missile, Tank, and Radar are defense equipment/systems developed by DRDO. Rifle is a general weapon, not specifically a DRDO product.


Question 8: Logical Reasoning

Problem: Statements:

  1. Some missiles are nuclear.
  2. All nuclear weapons are dangerous.

Conclusions: I. Some missiles are dangerous. II. All dangerous things are missiles.

Solution: I. Some missiles are dangerous - True (Some missiles → nuclear → dangerous) II. All dangerous things are missiles - False (Reverse is not true)


Question 9: Pattern Recognition

Problem: If 2 + 3 = 25, 4 + 5 = 81, 6 + 7 = 169, then 8 + 9 = ?

Solution: Pattern: (a + b)² 2 + 3 = 5² = 25 ✓ 4 + 5 = 9² = 81 ✓ 6 + 7 = 13² = 169 ✓

8 + 9 = 17² = 289


Question 10: Seating Arrangement

Problem: A, B, C, D, and E are sitting in a row. B is between A and E. D is to the right of E. C is to the left of A. Who is in the middle?

Solution: From the clues:

  • C ... A ... B ... E ... D
  • B is between A and E
  • D is right of E
  • C is left of A

Arrangement: C - A - B - E - D

Middle position: B
