    Question

    The average age of a team of 20 men is 36 years. If the

    total age of a group of 16 women is 20% less than the total age of the team of men, then what is the ratio between the average age of a man and that of a woman, respectively?
    A 3:5 Correct Answer Incorrect Answer
    B 2:3 Correct Answer Incorrect Answer
    C 1:1 Correct Answer Incorrect Answer
    D 2:1 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Total age of all men = 20 × 36 = 720 years

    So, total age of all women = 720 × 0.80 = 576 years

    So, average age of a woman = 576 ÷ 16 = 36 years

    Required ratio = 36:36 = 1:1
