  1. A pie chart shows market share: Brand A = 35%, Brand B = 25%, Brand C = 20%, Brand D = 12%, Others = 8%. If the total market is worth $5,000,000, what is Brand C's market value?

    Answer: $1,000,000

    Brand C = 20% × $5,000,000 = $1,000,000.

  2. A two-way table from a survey of 200 students shows: 80 males (50 prefer online learning) and 120 females (70 prefer online learning). What percentage of all students prefer online learning?

    Answer: 60%

    Total preferring online = 50 + 70 = 120; 120 / 200 × 100 = 60%.

  3. A table shows unit prices and quantities sold: Product X ($12, 250 units), Product Y ($18, 180 units), Product Z ($8, 400 units). Which product generated the highest revenue?

    Answer: Product Y ($3,240)

    X = $3,000; Y = $3,240; Z = $3,200 — Product Y generated the highest revenue.

  4. A frequency table shows test score ranges: 60–69 (8 students), 70–79 (15 students), 80–89 (12 students), 90–99 (5 students). What percentage of students scored 80 or above?

    Answer: 42.5%

    Students scoring 80+ = 12 + 5 = 17; total = 40; percentage = 17 / 40 × 100 = 42.5%.

  5. A pie chart shows how a student spends 24 hours: Sleep 33.3%, School 25%, Study 12.5%, Recreation 16.7%, Other 12.5%. Approximately how many hours per day are spent on recreation?

    Answer: 4 hours

    Recreation = 16.7% × 24 ≈ 4 hours.

  6. A table shows equipment rental rates: 1–3 days = $50/day, 4–6 days = $40/day, 7+ days = $30/day. What is the total rental cost for 8 days?

    Answer: $240

    8 days qualifies for the 7+ rate: 8 × $30 = $240.

  7. A contingency table shows: 280 employed (210 with a college degree) and 220 unemployed (80 with a college degree). What is the probability that a randomly selected person with a college degree is employed?

    Answer: 0.724

    Total with degree = 210 + 80 = 290; probability = 210 / 290 ≈ 0.724.
