    Question

    Incomes (in lakhs) of two persons A and B, over the years 2006-2010 are shown in the graph.

    Which of the following statements is true?

    A.

    Over the years, trends of income of A and B are the same.

    B.

    The largest difference in incomes of A and B is in the year 2008.

    C.

    During the given period, the average income of A is higher by 1.8 lakh compared to B.

    D.

    During the given period, the annual income of A was below its average more than twice.

    Correct option is D

    Given:
    The graph shows income (in lakhs) of persons A and B from 2006 to 2010.
    We need to identify the true statement based on the graph.

    Formula Used:

    Average=Total IncomeNumber of Years\text{Average} = \dfrac{\text{Total Income}}{\text{Number of Years}}

    Solution:

    Step 1: Read data from graph
    Approximate yearly incomes:

    Step 2: Find Average Incomes

    Total income of A = 6 + 5 + 4 + 5 + 6 = 26
    Average income of A = 26 / 5 = 5.2 lakhs
    Total income of B = 3 + 4 + 2 + 4 + 5 = 18
    Average income of B = 18 / 5 = 3.6 lakhs
    Difference in averages = 5.2 − 3.6 = 1.6 lakhs
    So, Option (c) is close, but it says 1.8, so we must reject it as incorrect.
    Let’s now verify all options one by one.

    Option (a):
    Over the years, trends of income of A and B are the same.
    Check trend:

    A: 6→5→4→5→6

    B: 3→4→2→4→5
    Different trends. So, False

    Option (b):
    The largest difference in incomes of A and B is in the year 2008.
    In 2008: A = 4, B = 2 → Difference = 2
    In 2006: A = 6, B = 3 → Difference = 3 (larger)
    So, False

    Option (c):
    Average income of A is higher by 1.8 lakh compared to B.
    We found difference is 1.6, not 1.8 → False

    Option (d):
    During the given period, the annual income of A was below its average more than twice.
    Average of A = 5.2
    A’s values: 6, 5, 4, 5, 6
    Values below average = 5, 4, 5 → 3 times
    So, True
    Final Answer: (d) During the given period, the annual income of A was below its average more than twice.
