Data Interpretation questions with solutions

6 from the 455-question pool, worked in full.

  1. 1. Read the data description and answer the question that follows. A biology class measured the height of bean plants grown under four different daily light exposures over two weeks. Group A received 4 hours of light per day and grew to an average height of 8 cm. Group B received 8 hours of light per day and grew to an average height of 14 cm. Group C received 12 hours of light per day and grew to an average height of 19 cm. Group D received 16 hours of light per day and grew to an average height of 17 cm. Soil type, water amount, and temperature were held constant across all four groups. Question: What does the data for Group D suggest about increasing light exposure beyond 12 hours per day?

    • A. Light exposure has no upper limit on benefiting growth
    • B. Beyond a certain point, additional light did not increase, and may have reduced, average height ✓
    • C. Group D received no light at all
    • D. Group D grew taller than every other group

    Solution. Height dropped from 19 cm at 12 hours (Group C) to 17 cm at 16 hours (Group D), suggesting a limit beyond which more light did not help.

  2. 2. Four incubator teams logged prototype-test hours and successful test cycles as follows: A: 36 hours, 9 cycles; B: 45 hours, 12 cycles; C: 40 hours, 8 cycles; D: 54 hours, 18 cycles. Which team had the highest successful cycles per test hour?

    • A. Team A
    • B. Team B
    • C. Team D ✓
    • D. Team C

    Solution. Cycles per hour are A=.25, B≈.267, C=.20, D=.333; D is highest.

  3. 3. A survey of 400 households records preferred payment method: Cash 90, Card 130, UPI 150, Other 30. If one household is selected at random, what is the probability it prefers Card or UPI?

    • A. 0.70 ✓
    • B. 0.55
    • C. 0.65
    • D. 0.75

    Solution. Card or UPI households=130+150=280. Probability=280/400=0.70.

  4. 4. Study the table below showing the number of loan applications processed by five bank branches over a quarter, and answer the question that follows. Branch | Personal Loans | Home Loans | Business Loans A | 140 | 80 | 50 B | 160 | 70 | 40 C | 120 | 90 | 35 D | 150 | 75 | 45 E | 130 | 85 | 30 What percentage of Branch E's total loan applications are Home Loans? (approximate to one decimal)

    • A. 34.7% (approx) ✓
    • B. 40%
    • C. 30%
    • D. 38%

    Solution. Branch E total = 130+85+30 = 245. Home Loans = 85. Percentage = (85/245) × 100 ≈ 34.7%.

  5. 5. A branch opened 90 accounts in April, 110 in May, and 130 in June. What was the monthly average?

    • A. 110 ✓
    • B. 105
    • C. 115
    • D. 120

    Solution. Average = (90 + 110 + 130) / 3 = 330 / 3 = 110.

  6. 6. A branch opened 60 accounts in April, 80 in May, and 100 in June. What was the monthly average?

    • A. 75
    • B. 80 ✓
    • C. 78
    • D. 82

    Solution. Average = (60 + 80 + 100) / 3 = 240 / 3 = 80.
