    Question

    X and Y are two numbers. Their average is 280, and the

    sum of X and Y is 160% of X. What percentage of X is the difference between X and Y?
    A 40% Correct Answer Incorrect Answer
    B 20% Correct Answer Incorrect Answer
    C 29% Correct Answer Incorrect Answer
    D 18% Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ;
    Since A + B = 140% of A

    So, A : B = 5 : 3

    (A − B) : A = 2 : 5

    Therefore,

    2/5 × 100% = 40%
