    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ,

    Number of boys in town = {3 / (3 + 5)} ├Ч 2400 = 900

    Number of girls in town = {5 / (3 + 5)} ├Ч 2400 = 1500

    According to question,

    900 : (1500 + 200) = 18 : x

    900 : 1700 = 18 : x

    18 : 34 = 18 : x

    Therefore, x = 34

    So, (18 тАУ x) = 18 тАУ 34 = тАУ16
