    B 39:26 Correct Answer Incorrect Answer
    C 80:69 Correct Answer Incorrect Answer
    D 65:61 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let the number of boys in the team be x

    So, number of girls in the team = x + 16

    So, x + x + 16 = 80

    Or, 2x = 64

    So, x = 32

    So, number of boys in the team = 32

    And number of girls in the team = 32 + 16 = 48

    And number of girls added to the team = 50 × 60% = 30

    And number of boys added to the team = 50 - 30 = 20

    So, required ratio = (48 + 30) : (32 + 20) = 78 : 52 = 39 : 26
