Problem-Solving and Data Analysis practice question
A shop's monthly sales rose from $30,000 in April to $40,000 in May. By what percent did sales increase? Round to the nearest whole percent.
Answer: 33
Increase: 10,000. As a share of April's 30,000: 10,000/30,000 = 1/3 ≈ 33%.
Common wrong answers
- If you answered 10
- 10 is the increase in thousands of dollars, not a percent.
- If you answered 25
- 25% divides the increase by MAY's figure (10,000/40,000); percent increase uses the starting value.
- If you answered 75
- 75% is April as a percent of May (30/40), not the increase.
