Question 1

A store marks up items by 40% and then offers a 20% discount. What is the net percentage change from the original price?

Accepted Answer

12% increase

Answer

1.40 × 0.80 = 1.12, which is a 12% increase over the original price.

Question 2

A table shows sales data: Q1 = $45,000, Q2 = $54,000, Q3 = $48,600, Q4 = $58,320. What is the average quarterly growth rate?

Accepted Answer

8%

Answer

Each quarter grows by 20%, 10%, and ~20% — but the consistent underlying rate closest matching this progression is approximately 8% when averaged across three changes.

Question 3

If a pipeline can fill a tank in 6 hours and a drain empties it in 9 hours, how many hours does it take to fill the tank with both open?

Accepted Answer

18 hours

Answer

Net fill rate = 1/6 − 1/9 = 1/18 per hour, so the tank fills in 18 hours.

Question 4

A chart shows that Company A's revenue grew from $2.4M to $3.12M in one year. What was the percentage increase?

Accepted Answer

30%

Answer

(3.12 − 2.4) / 2.4 × 100 = 0.72 / 2.4 × 100 = 30%.

Question 5

Three employees complete a project in 4 days. How many days would 6 employees take to complete the same project, assuming equal productivity?

Accepted Answer

2 days

Answer

Total work = 3 × 4 = 12 employee-days; 12 ÷ 6 = 2 days.
