GGST Numerical Reasoning: Data Interpretation 5

Question 1

A table shows staff satisfaction scores (out of 10) across 5 offices: 7.2, 6.8, 8.1, 7.5, 6.9. What is the mean satisfaction score across all offices?

Accepted Answer

7.3

Answer

(7.2+6.8+8.1+7.5+6.9)/5 = 36.5/5 = 7.3.

Question 2

A chart shows that a program served 4,200 beneficiaries in Year 1 and grew by 15% in Year 2 and 10% in Year 3. How many beneficiaries were served in Year 3?

Accepted Answer

5,313

Answer

Year 2 = 4,200 × 1.15 = 4,830; Year 3 = 4,830 × 1.10 = 5,313.

Question 3

A table shows the ratio of managers to staff in four departments: A=1:8, B=1:12, C=1:10, D=1:6. Department B has 3 managers. How many total staff (including managers) are in Department B?

Accepted Answer

39

Answer

3 managers × 12 staff each = 36 staff + 3 managers = 39 total.

Question 4

A bar chart shows procurement spending by category ($000s): Equipment=850, Software=320, Services=640, Supplies=190. By how much does Equipment spending exceed the average of the other three categories?

Accepted Answer

$438K

Answer

Average of others = (320+640+190)/3 = 383.3K; 850 − 383.3 ≈ $467K — closest is $466K.

Question 5

A table shows leave days taken per employee across a team of 6: 12, 8, 15, 10, 8, 13. What is the mode of leave days taken?

Accepted Answer
