    As per first graph,
    The number of students in Collage A = Total number of students x 21%
    As per second graph,
    The number of girls form College A = Total number of girls x 23%

    Correct Option: C

    As per first graph,
    The number of students in Collage A = Total number of students x 21%
    The number of students in Collage A = 3500 x 21/100
    The number of students in Collage A = 35 x 21 = 735
    As per second graph,
    The total number of girls from College A = Total number of girls x 23%
    The total number of girls from College A = 1800 x 23/100
    The total number of girls from College A = 18 x 23 = 414
    Number of boys from college A = Total number of students in Collage A - The total number of girls from College A
    Since, number of boys from college A = 735 - 414 = 321
    Required percentage = 100 x Number of Boys from Collage A / Total number of boys in collage A
    Required percentage = 100 x 321/735
    Required percentage = 2140/49 = 43.67%

  1. What is the total number of boys from Colleges E and F together?

    As per first graph,
    The number of students in Collage E = Total number of students x 7%
    As per second graph,
    The number of girls from College E = Total number of girls x 8%
    So number of boys in Collage E = The total number of students in Collage E - The total number of girls in Collage E.
    Similarly for other collage also apply the same formula.

    Correct Option: A

    As per first graph,
    The number of students in Collage E = Total number of students x 7%
    As per second graph,
    The number of girls from College E = Total number of girls x 8%
    So number of boys in Collage E = The total number of students in Collage E - The total number of girls in Collage E.
    Number of boys from college E = 3500 x 7/100 - 1800 x 8/100
    Number of boys from college E = 35 x 7 - 18 x 8
    Number of boys from college E = 245 - 144 = 101
    Similarly for collage F also apply the same formula.
    Number of boys from college F = 3500 x 12/100 - 1800 x 17/100 = 420 - 306 = 114
    Hence, the total number of boys together in collage E and F = 101 + 114 = 215

  1. What is the number of girls in college D?








  1. View Hint View Answer Discuss in Forum

    As per second graph,
    Total number of girls = 1800
    Number of girls in College D = Total Number of Girls x 11%

    Correct Option: D


    As per second graph,
    Total number of girls = 1800
    Number of girls in College D = Total Number of Girls x 11%
    ⇒ Number of girls in College D = 1800 x 11%
    ⇒ Number of girls in College D = 1800 x 11/100
    ⇒ Number of girls in College D = 18 x 11 = 198
