    Question

    Study the following bar graph and answer the question that follows.

    In which year was the number of accounts approximately 15% of the total number of accounts in all the years.

    A.

    Mar 2012

    B.

    Mar 2010

    C.

    Mar 2011

    D.

    Mar 2013

    Correct option is B

    Given:

    Number of BSBD accounts:

    March 2010 = 73.45 million

    March 2011 = 104.76 million

    March 2012 = 138.5 million

    March 2013 = 182.06 million

    Required: Find the year in which the number of accounts ≈ 15% of the total across all years

    Solution:

    Total accounts=73.45 + 104.76 + 138.5 + 182.06 = 498.77 million

    15% of total =15100×498.77=74.82 million (approx)= \frac{15}{100} \times 498.77 = 74.82 \text{ million (approx)}​​

    Now compare 74.82 million with the yearly values:

    March 2010 = 73.45 million → Closest to 74.82 million

    Answer: March 2010
