    A and B are two numbers. Their average is 220, and the

    sum of A and B is 150% of A. What percentage of A is the difference between A and B?
    A 22% Correct Answer Incorrect Answer
    B 20% Correct Answer Incorrect Answer
    C 29% Correct Answer Incorrect Answer

    Solution

    ATQ;

    Since A + B = 150% of A

    So, A : B = 2 : 3

    (A − B) : A = 1 : 5

    Therefore,

    1/5 × 100% = 20%
