Numerical ability questions
Q1: CI vs SI hint
Problem: Find compound interest on ₹10,000 at 10% per annum for 2 years, compounded annually.
Solution: Amount = 10000 × (1.1)² = 10000 × 1.21 = ₹12,100. CI = 12100 − 10000 = ₹2100. (SI for same period would be ₹2000; the extra ₹100 is interest on first-year interest.)
Answer: ₹2100
Q2: Partnership share
Problem: A and B invest ₹40,000 and ₹60,000. If profit is ₹25,000, what is A’s share?
Solution: Ratio A:B = 2:3. A’s share = (2/5) × 25000 = ₹10,000.
Answer: ₹10,000
Q3: Population growth
Problem: A town’s population is 20,000. It grows 10% yearly. Population after 2 years?
Solution: After 2 years: 20000 × 1.1 × 1.1 = 24200.
Answer: 24,200
Q4: Discount successive
Problem: Two successive discounts of 10% and 20% equal a single discount of?
Solution: Net multiplier = 0.9 × 0.8 = 0.72 → 28% single discount.
Answer: 28%
Q5: Percentage of percentage
Problem: What is 15% of 20% of 400?
Solution: 20% of 400 = 80. 15% of 80 = 12.
Answer: 12
Q6: Number digit sum
Problem: Sum of digits of a two-digit number is 9. If digits are reversed, number increases by 27. Original number?
Solution: 10a+b; a+b=9; 10b+a = 10a+b+27 → 9b−9a=27 → b−a=3. a+b=9, b−a=3 → b=6, a=3. Number = 36.
Answer: 36
Q7: Fraction simplify
Problem: Simplify: (3/4) ÷ (9/8) × (2/3).
Solution: (3/4) × (8/9) × (2/3) = (3×8×2)/(4×9×3) = 48/108 = 4/9.
Answer: 4/9
Q8: Remainder theorem style
Problem: Find remainder when 7^3 is divided by 5.
Solution: 343 ÷ 5: 5×68=340, remainder 3. Or 7≡2 mod 5; 2³=8≡3.
Answer: 3
Q9: Train and pole
Problem: A train 150 meters long passes a pole in 15 seconds. What is its speed in km/h?
Solution: Distance = 150 m = 0.15 km. Time = 15 s = 15/3600 h = 1/240 h. Speed = 0.15 ÷ (1/240) = 0.15 × 240 = 36 km/h.
Faster check: 150/15 = 10 m/s → 10 × 18/5 = 36 km/h.
Answer: 36 km/h
Q10: Average speed
Problem: A person covers a distance at 60 km/h and returns at 40 km/h. What is the average speed for the whole trip?
Solution: For equal distances, average speed = 2ab/(a+b). = 2×60×40 / (60+40) = 4800/100 = 48 km/h.
Do not take the arithmetic mean (50); that would be wrong here.
Answer: 48 km/h
