Data Interpretation questions with solutions

6 from the 449-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. The table below shows the number of policies renewed by four branches over two quarters. One value is missing and must be calculated from the given total. Study the table and answer the question that follows. Branch | Q1 | Q2 | Total P | 130 | 150 | 280 Q | 120 | ? | 250 R | 145 | 160 | 305 S | 110 | 140 | 250 Grand total (all branches, both quarters) = 1085 What is the missing value (Branch Q's Q2 renewals)?

    • A. 130 ✓
    • B. 125
    • C. 135
    • D. 120

    Solution. Branch Q's total is 250, and Q1 = 120, so Q2 = 250 − 120 = 130.

  3. 3. A pie chart shows a bank's loan portfolio: Retail 35%, Corporate 30%, Agriculture 20%, Others 15%. If the total portfolio is ₹40,000 crore, find the value of Corporate loans.

    • A. ₹10,000 crore
    • B. ₹11,000 crore
    • C. ₹12,000 crore ✓
    • D. ₹13,000 crore

    Solution. 30% of ₹40,000 crore = 0.30 × 40,000 = ₹12,000 crore.

  4. 4. Using the data above, find the percentage increase in consumption from February to March.

    • A. 20% ✓
    • B. 15%
    • C. 25%
    • D. 30%

    Solution. Consumption rose from 150 to 180, a rise of 30. As a share of 150 that is 20%.

  5. 5. The bar chart shows books sold by a store over 4 months: January 100, February 150, March 120, April 150. Find the average books sold per month.

    • A. 120
    • B. 125
    • C. 130 ✓
    • D. 135

    Solution. Total books sold = 100 + 150 + 120 + 150 = 520. Average = 520 / 4 = 130.

  6. 6. Study the table below showing the number of new life insurance policies sold by five LIC branches over three consecutive months, and answer the question that follows. Branch | Apr | May | Jun V | 220 | 205 | 240 W | 190 | 215 | 180 X | 250 | 230 | 265 Y | 150 | 175 | 200 Z | 200 | 190 | 225 What is the ratio of Branch Y's April policies to Branch Z's April policies?

    • A. 3:4 ✓
    • B. 2:3
    • C. 4:5
    • D. 3:5

    Solution. Y's April = 150, Z's April = 200. Ratio = 150:200, which simplifies (dividing by 50) to 3:4.
