HAST Quantitative Reasoning 2 — Questions and Answers
Question 1: A car uses 6 liters of fuel per 100 km. How much fuel is needed for a 250 km trip?
- 15 liters (Correct answer)
- 12 liters
- 18 liters
- 20 liters
Correct answer: 15 liters
Fuel = (6 ÷ 100) × 250 = 15 liters.
Question 2: The average of five numbers is 12. If four of the numbers are 10, 11, 13, and 14, what is the fifth?
- 12 (Correct answer)
- 11
- 13
- 10
Correct answer: 12
Total = 5 × 12 = 60; sum of known numbers = 10 + 11 + 13 + 14 = 48; fifth number = 60 − 48 = 12.
Question 3: A square has perimeter 36 cm. What is its area?
- 81 cm² (Correct answer)
- 72 cm²
- 64 cm²
- 100 cm²
Correct answer: 81 cm²
Side = 36 ÷ 4 = 9 cm; area = 9² = 81 cm².

- Lower than original (Correct answer)
- Higher than original
- Same as original

Correct answer: Lower than original
Increasing then decreasing by 20% gives 1.2 × 0.8 = 0.96 times the original, which is 4% lower.
Question 5: What is 15% of 200?
