- 20%
- 25% (Correct answer)
- 15%
- 30%
Correct answer: 25%
Percentage increase = (3.0 - 2.4) / 2.4 × 100 = 0.6 / 2.4 × 100 = 25%.
Question 2: A bar chart shows sales of 500, 750, 600, and 900 units in four quarters. What is the mean quarterly sales figure?
- 662.5
- 687.5 (Correct answer)
- 712.5
- 725
Correct answer: 687.5
Mean = (500 + 750 + 600 + 900) / 4 = 2750 / 4 = 687.5.
Question 3: A pie chart shows market share: Company A has 35%, B has 25%, C has 20%, and D has the remainder. If total market revenue is $8 million, how much does Company D earn?
- $1.2 million
- $1.4 million
- $1.6 million (Correct answer)
- $1.8 million
Correct answer: $1.6 million
Company D has 100% - 35% - 25% - 20% = 20% share; 20% of $8M = $1.6 million.

- 15%
- 20% (Correct answer)
- 25%
- 30%
Correct answer: 20%
Total = 1,200 + 300 = 1,500; part-time percentage = 300 / 1,500 × 100 = 20%.
Question 5: A line graph shows that a stock price rose from $40 to $52 over one year. What is the percentage return?
- 24%
- 26%
- 28%
- 30% (Correct answer)

Percentage return = (52 - 40) / 40 × 100 = 12 / 40 × 100 = 30%.
