Question 1

A project earned $84,000 in revenue and incurred $61,500 in costs. What is the profit margin (profit as a percentage of revenue)?

Accepted Answer

26.8%

Answer

Profit = $84,000 − $61,500 = $22,500; margin = 22,500 ÷ 84,000 × 100 ≈ 26.8%.

Question 2

A water tank holds 12,000 liters. A pipe fills it at 80 liters/min while a drain removes 20 liters/min simultaneously. How long to fill the tank from empty?

Accepted Answer

200 min

Answer

Net fill rate = 80 − 20 = 60 liters/min; time = 12,000 ÷ 60 = 200 min.

Question 3

Staff salaries increased from an average of $3,200/month to $3,680/month. By what percentage did the average salary increase?
