IMSA Data Interpretation and Word Problems 2 — Questions and Answers
Question 1: A pie chart shows 30% of a company's budget goes to marketing. If the total budget is $500,000, how much is spent on marketing?
- $150,000 (Correct answer)
- $300,000
- $50,000
- $30,000
Correct answer: $150,000
30% of $500,000 = 0.30 × 500,000 = $150,000.
Question 2: The mode of the dataset {4, 7, 2, 7, 9, 4, 7} is:
- 7 (Correct answer)
- 4
- 2
- 9
Correct answer: 7
7 appears three times, more than any other value, so the mode is 7.
Question 3: A student scored 78, 85, 90, and 67 on four tests. What score is needed on a fifth test to average 80?
- 80 (Correct answer)
- 100
- 85
- 90
Correct answer: 80
Total needed = 80 × 5 = 400; current sum = 78+85+90+67 = 320; needed = 400 − 320 = 80.
Question 4: A line graph shows temperatures: Mon 68°, Tue 72°, Wed 65°, Thu 70°, Fri 75°. What is the range?
- 10° (Correct answer)
- 7°
- 72°
- 68°
Correct answer: 10°
Range = maximum − minimum = 75 − 65 = 10°.
Question 5: If a store marks up an item by 40% and the original cost is $30, what is the selling price?
- $42 (Correct answer)
- $40
- $12
- $70
Correct answer: $42
Markup = 40% of $30 = $12; selling price = $30 + $12 = $42.
Question 6: A recipe calls for 2.5 cups of flour per dozen cookies. How much flour is needed for 60 cookies?
- 12.5 cups (Correct answer)
- 10 cups
- 25 cups

Correct answer: 12.5 cups
60 cookies = 5 dozens; flour needed = 5 × 2.5 = 12.5 cups.
