GAT Quantitative Reasoning 2 — Questions and Answers
Question 1: If the ratio of boys to girls in a Saudi school class is 3:5 and there are 40 students total, how many boys are there?
- 12
- 15 (Correct answer)
- 18
- 24
Correct answer: 15
Total ratio parts = 3 + 5 = 8. Each part = 40 ÷ 8 = 5 students. Boys = 3 × 5 = 15. Ratio problems are a fundamental part of the Qudurat quantitative section.
Question 2: A water tank holds 1,200 liters. If it is 75% full, how many more liters are needed to fill it completely?
- 200 liters
- 300 liters (Correct answer)
- 400 liters
- 900 liters
Correct answer: 300 liters
75% full = 0.75 × 1,200 = 900 liters. Remaining = 1,200 - 900 = 300 liters. This combines percentage and subtraction skills.
Question 3: What is the probability of rolling an even number on a standard six-sided die?
- 1/6
- 1/3
- 1/2 (Correct answer)
- 2/3
Correct answer: 1/2
Even numbers on a die: 2, 4, 6 = 3 favorable outcomes out of 6 total. Probability = 3/6 = 1/2. Basic probability is tested in the Qudurat exam.
Question 4: Ahmad saved SAR 200 per month for 18 months. He then spent SAR 1,500 on a laptop. How much does he have left?
- SAR 1,100
- SAR 2,100 (Correct answer)
- SAR 2,400
- SAR 3,600
Correct answer: SAR 2,100
Total saved = 200 × 18 = SAR 3,600. After spending = 3,600 - 1,500 = SAR 2,100. This tests multiplication and subtraction in a real-world context.
Question 5: The mean of five numbers is 24. If four of the numbers are 20, 22, 26, and 28, what is the fifth number?
- 20
- 22
- 24 (Correct answer)
- 28
Correct answer: 24
Sum of all five = Mean × Count = 24 × 5 = 120. Sum of four known numbers = 20 + 22 + 26 + 28 = 96. Fifth number = 120 - 96 = 24.
Question 6: A circle has a radius of 7 cm. What is its circumference? (Use π ≈ 22/7)
- 22 cm
- 44 cm (Correct answer)
- 154 cm
- 88 cm
Correct answer: 44 cm
Circumference = 2πr = 2 × (22/7) × 7 = 2 × 22 = 44 cm. The 7s cancel, making this a clean calculation. Circle formulas appear regularly on the Qudurat.
