    E None of these Correct Answer Incorrect Answer

    Solution

    Let the total boys be x and the total girls be (65 - x).
    Total amount which the boys get = x * 2(6/13)% of 65 = x * (32/13)% of 65 = 8x/5
    Total amount which the girls get = (65 - x) * 12/13 % of 65 = 39 - 3x/5
    According to the question-
    => 8x/5 + 39 - 3x/5 = 78
    => x + 39 = 78
    => x=39
    Ratio of boys to the girls = 39:(65 - 39) = 39:26 = 3:2
