    C 5: 8 Correct Answer Incorrect Answer
    D 3: 5 Correct Answer Incorrect Answer

    Solution

    Let the number of boys be x, then, the number of girls be x +16. Now, according to question: x+x+16= 64 2x=64-16 x = 48/2=24 Hence, the number of boys x = 24 and The number of total students who took part in quiz = 64 Hence, the required ratio = 24: 64 = 3:8
