GAT Data Interpretation 1 — Questions and Answers
Question 1: A bar chart shows Saudi oil production: 2020: 9M barrels/day, 2021: 9.5M, 2022: 10.5M, 2023: 10M. What was the percentage increase from 2020 to 2022?
- 10.5%
- 15.8%
- 16.7% (Correct answer)
- 20%
Correct answer: 16.7%
Percentage increase = ((10.5 - 9) / 9) × 100 = (1.5/9) × 100 = 16.67% ≈ 16.7%. Always calculate percentage change relative to the original value.
Question 2: A pie chart shows a Saudi household budget: Housing 35%, Food 25%, Transport 15%, Education 15%, Other 10%. If the monthly income is SAR 12,000, how much is spent on food?
- SAR 2,000
- SAR 2,500
- SAR 3,000 (Correct answer)
- SAR 4,200
Correct answer: SAR 3,000
Food spending = 25% × 12,000 = SAR 3,000. Reading pie charts and converting percentages to actual amounts is a key data interpretation skill.
Question 3: A table shows exam scores for 5 Saudi regions. If the Eastern Province averaged 78 and had 200 students, while Riyadh averaged 82 with 300 students, what is the combined average?
- 79.2
- 80.0
- 80.4 (Correct answer)
- 81.6
Correct answer: 80.4
Combined average = (78×200 + 82×300) / (200+300) = (15,600 + 24,600) / 500 = 40,200 / 500 = 80.4. Weighted averages require considering the group sizes.
Question 4: A line graph shows temperature in Riyadh across 4 months: Jan 15°C, Feb 18°C, Mar 24°C, Apr 30°C. What is the average monthly temperature increase?
- 3°C
- 4°C
- 5°C (Correct answer)
- 6°C
Correct answer: 5°C
Total increase = 30 - 15 = 15°C over 3 intervals (Jan→Feb, Feb→Mar, Mar→Apr). Average increase = 15/3 = 5°C per month.
Question 5: A table shows Saudi university enrollment: Engineering 1,200, Medicine 800, Business 2,000, IT 1,000. What fraction of total enrollment is in Business?
- 1/5
- 2/5 (Correct answer)
- 1/4
- 1/3
Correct answer: 2/5
Total enrollment = 1,200 + 800 + 2,000 + 1,000 = 5,000. Business fraction = 2,000/5,000 = 2/5. Converting data to fractions tests both arithmetic and data reading skills.
Question 6: Sales data shows: Q1: SAR 50,000, Q2: SAR 65,000, Q3: SAR 55,000, Q4: SAR 80,000. Which quarter had the highest growth rate compared to the previous quarter?
- Q2 (30% growth)
- Q3 (decline)
- Q4 (45.5% growth) (Correct answer)
- Q2 and Q4 are equal
Correct answer: Q4 (45.5% growth)
Q2 growth: (65-50)/50 = 30%. Q3: decline. Q4 growth: (80-55)/55 = 45.5%. Q4 had the highest growth rate at 45.5%.
