🧮 Quantitative Aptitude Questions (15 with Solutions)

Question 1: Simplification

Q: (2.5 × 4.8) + (3.6 × 5.5) - (1.8 × 3.2) = ?

Solution: = 12.0 + 19.8 - 5.76 = 31.8 - 5.76 = 26.04

Question 2: Number System

Q: The HCF of two numbers is 15 and their LCM is 300. If one number is 60, find the other.

Solution: Product of numbers = HCF × LCM 60 × other = 15 × 300 Other = (15 × 300)/60 = 75

Question 3: Percentage

Q: If 15% of 40 is greater than 25% of a number by 2, find the number.

Solution: 15% of 40 = 6 Let the number be x 25% of x = 6 - 2 = 4 x = 4 × 4 = 16

Question 4: Profit & Loss

Q: A shopkeeper sells two articles each for ₹1,500. On one he gains 25% and on the other he loses 25%. What is his overall profit or loss?

Solution: CP of first article = 1500 × 100/125 = ₹1,200 CP of second article = 1500 × 100/75 = ₹2,000 Total CP = ₹3,200 Total SP = ₹3,000

Loss = 200 Loss% = 200/3200 × 100 = 6.25%

Shortcut: When SP is same and profit% = loss%, there is always loss of (x²/100)% Loss% = (25 × 25)/100 = 6.25% Answer: 6.25% Loss

Question 5: Average

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

Solution: Let numbers be: x, x+2, x+4, x+6, x+8 Average = (5x + 20)/5 = 25 5x + 20 = 125 5x = 105 x = 21

Largest = x + 8 = 29

Shortcut: Average of consecutive odd numbers is the middle number So numbers are: 21, 23, 25, 27, 29 Answer: 29

Question 6: Ratio & Proportion

Q: Two numbers are in the ratio 5:7. If 9 is added to each, they are in the ratio 7:9. Find the smaller number.

Solution: Let numbers be 5x and 7x (5x + 9)/(7x + 9) = 7/9 45x + 81 = 49x + 63 4x = 18 x = 4.5

Smaller number = 5x = 22.5

Question 7: Simple Interest

Q: The simple interest on a sum of money is 1/9 of the principal, and the number of years is equal to the rate percent per annum. Find the rate.

Solution: Let Principal = P, Rate = R%, Time = R years SI = P/9

SI = (P × R × R)/100 P/9 = PR²/100 R² = 100/9 R = 10/3 = 3.33%

Question 8: Compound Interest

Q: The difference between compound interest and simple interest on ₹5,000 for 2 years at 4% per annum is:

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

Question 9: Time & Work

Q: A, B, and C can complete a work in 10, 15, and 20 days respectively. They start together but A leaves after 2 days and B leaves 3 days before completion. How many days did the work take?

Solution: Let total days = x Work done by A = 2/10 Work done by B = (x-3)/15 Work done by C = x/20

2/10 + (x-3)/15 + x/20 = 1 Multiply by 60: 12 + 4(x-3) + 3x = 60 12 + 4x - 12 + 3x = 60 7x = 60 x = 60/7 ≈ 8.57 days ≈ 9 days

Question 10: Time & Distance

Q: A train 180m long is running at 72 km/hr. How long will it take to cross a platform 220m long?

Solution: Total distance = 180 + 220 = 400m Speed = 72 × 5/18 = 20 m/s Time = 400/20 = 20 seconds

Question 11: Mensuration

Q: The area of a square is equal to the area of a rectangle with sides 16m and 9m. Find the perimeter of the square.

Solution: Area of rectangle = 16 × 9 = 144 sq.m Side of square = √144 = 12m Perimeter = 4 × 12 = 48m

Question 12: Algebra

Q: If x + y = 7 and xy = 12, find x² + y².

Solution: x² + y² = (x + y)² - 2xy = 49 - 24 = 25

Question 13: Partnership

Q: A and B invest in a business in the ratio 3:5. If 10% of the total profit goes to charity and A's share is ₹8,550, find the total profit.

Solution: Let total profit = P Profit after charity = 0.9P

A's share = (3/8) × 0.9P = 8550 2.7P/8 = 8550 P = 8550 × 8/2.7 = ₹25,333.33

Question 14: Data Interpretation

Q: In a school, 45% students are girls. If the number of boys is 440, find the total number of students.

Solution: Boys = 100% - 45% = 55% 55% = 440 1% = 8 Total = 100% = 800

Question 15: Mixtures

Q: In what ratio should water be mixed with milk costing ₹60 per liter to get a mixture worth ₹45 per liter?

Solution: Using Alligation: Water (₹0) _______ Milk (₹60) \ / (₹45)/ /
(60-45) (45-0) =15 =45

Ratio = 15:45 = 1:3

🧩 Reasoning Ability Questions (10 with Solutions)

Question 1: Series Completion

Q: 5, 11, 23, 47, 95, ?

Solution: Pattern: ×2 + 1 5 × 2 + 1 = 11 11 × 2 + 1 = 23 23 × 2 + 1 = 47 47 × 2 + 1 = 95 95 × 2 + 1 = 191

Question 2: Coding-Decoding

Q: If SYSTEM is coded as SYSMET and NEARER as AENRER, then FRACTION is coded as:

Solution: SYSTEM → SYSMET (swap last three letters: TEM → MET) NEARER → AENRER (swap first and middle: NEAR → AENR)

Pattern seems complex. For FRACTION: FRACTION → CARFNOIT (likely)

Question 3: Analogy

Q: Ink : Pen :: Petrol : ?

Solution: Ink is used in pen, Petrol is used in car.

Question 4: Blood Relations

Q: A woman introduces a man as "He is the only son of my mother's mother." How is the man related to the woman?
