Question 1

A country's GDP grew from $800 billion to $920 billion over five years. What was the total percentage increase?

Accepted Answer

15%

Answer

Percentage increase = (920 - 800) / 800 × 100 = 120 / 800 × 100 = 15%.

Question 2

If the probability of event A is 0.4 and the probability of event B is 0.3, and the events are independent, what is the probability that both A and B occur?

Accepted Answer

0.12

Answer

For independent events, P(A and B) = P(A) × P(B) = 0.4 × 0.3 = 0.12.

Question 3

An embassy processes visa applications at a rate of 120 per day with 6 staff. If staff increases to 9, how many applications per day can be processed (assuming linear scaling)?

Accepted Answer

180

Answer

Rate per staff = 120/6 = 20; with 9 staff: 9 × 20 = 180 applications per day.

Question 4

What is the median of the following dataset: 14, 7, 21, 3, 19, 11, 8?

Accepted Answer

11

Answer

Sorted: 3, 7, 8, 11, 14, 19, 21 — the middle (4th) value is 11.

Question 5

A diplomat travels 240 miles at 60 mph and returns the same distance at 40 mph. What is the average speed for the entire trip?

Accepted Answer

48 mph

Answer

Average speed = 2 × (60 × 40) / (60 + 40) = 4800 / 100 = 48 mph.
