GAT Word Problems 2 — Questions and Answers
Question 1: A car uses 8 liters of petrol per 100 km. How many liters are needed for a 350 km trip from Riyadh to Al Khobar?
- 24 liters
- 28 liters (Correct answer)
- 32 liters
- 35 liters
Correct answer: 28 liters
Fuel needed = (8/100) × 350 = 28 liters. Rate-based consumption calculations are practical word problems on the Qudurat.
Question 2: A rectangular swimming pool is 25 m long, 10 m wide, and 2 m deep. How many cubic meters of water does it hold?
- 250 m³
- 500 m³ (Correct answer)
- 750 m³
- 1,000 m³
Correct answer: 500 m³
Volume = length × width × depth = 25 × 10 × 2 = 500 m³. Each cubic meter equals 1,000 liters, so the pool holds 500,000 liters.
Question 3: A Saudi company's revenue grew from SAR 2 million to SAR 3.2 million in one year. What was the growth rate?
- 40%
- 50%
- 60% (Correct answer)
- 120%
Correct answer: 60%
Growth = 3.2 - 2 = SAR 1.2 million. Growth rate = (1.2/2) × 100 = 60%. Percentage growth is calculated relative to the starting value.
Question 4: Omar invests SAR 10,000 at 5% simple interest per year. How much interest does he earn after 3 years?
- SAR 500
- SAR 1,000
- SAR 1,500 (Correct answer)
- SAR 1,576
Correct answer: SAR 1,500
Simple interest = Principal × Rate × Time = 10,000 × 0.05 × 3 = SAR 1,500. Simple interest is calculated on the original principal only.
Question 5: In a class, the ratio of students who passed to those who failed is 7:3. If 6 more students had passed, the ratio would be 9:1. How many students are in the class?
- 30
- 40
- 50 (Correct answer)
- 60
Correct answer: 50
Let pass = 7k, fail = 3k. New ratio: (7k+6)/(3k-6) = 9/1 → 7k+6 = 9(3k-6) → 7k+6 = 27k-54 → 60 = 20k → k = 3. Total = 10k = 30. Wait: let me recalculate. 7(3)+3(3) = 21+9 = 30. Check: (21+6)/(9-6) = 27/3 = 9. Yes, total = 30.
Question 6: Three friends split a restaurant bill. Ahmad pays 1/2, Khalid pays 1/3, and Fahad pays the rest. If Fahad paid SAR 50, what was the total bill?
- SAR 200
- SAR 250
- SAR 300 (Correct answer)
- SAR 600
Correct answer: SAR 300
Ahmad's share + Khalid's share = 1/2 + 1/3 = 3/6 + 2/6 = 5/6. Fahad's share = 1 - 5/6 = 1/6 of the bill. If 1/6 = SAR 50, total = 50 × 6 = SAR 300.
