GAT Data Interpretation

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?

Accepted Answer

16.7%

Answer

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?

Accepted Answer

SAR 3,000

Answer

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?

Accepted Answer

80.4

Answer

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?

Accepted Answer

5°C

Answer

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?

Accepted Answer

2/5

Answer

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.
