    ∵ Total boys = 45 + 186 +120 +100 + 65 + 32 + 58 + 5 = 611

    Total number of girls = 25 + 23 + 25 + 12 + 25 + 20 + 12 + 3 = 145

    Correct Option: D

    ∵ Total boys = 45 + 186 +120 +100 + 65 + 32 + 58 + 5 = 611
    ∴ Number of boys who pass in their respective courses = 60% of 611 = 611 x 60/100 = 366.60
    Total number of girls = 25 + 23 + 25 + 12 + 25 + 20 + 12 + 3 = 145
    Number of girls who pass in their respective courses =70% of 145= 145 x 70/100 = 101.50
    ∴ Combined pass percent = (366.6 + 101.5) x 100/(611 + 145) = 46810/756 = 61.92 = 62%

    Total number of boys = 45 + 65 + 186 + 32 + 120 + 58 + 100 + 5 = 611
    Total number of girls = 25 + 23 + 25 + 12 + 25 + 20 + 12 + 3 = 145

    Correct Option: A

    Total number of boys = 45 + 65 + 186 + 32 + 120 + 58 + 100 + 5 = 611
    Total number of girls = 25 + 23 + 25 + 12 + 25 + 20 + 12 + 3 = 145
    ∴ Required percentage = (611 - 145/145) x 100 ≈ 321%
