    Question

    Present age of ‘P’ is 60% more than that of ‘Q’.

    8 years ago, ‘P’ was twice as old as ‘Q’. Find the present age of ‘Q’.
    A 16 years Correct Answer Incorrect Answer
    B 18 years Correct Answer Incorrect Answer
    C 20 years Correct Answer Incorrect Answer
    D 22 years Correct Answer Incorrect Answer

    Solution

    Let the present age of ‘Q’ be ‘x’ years
    Therefore, present age of ‘P’ = 1.6x years
    ATQ;
    (1.6x – 8) = 2 × (x – 8)
    Or, 1.6x – 8 = 2x – 16
    Or, 8 = 0.4x
    Or, x = 20
    Therefore, present age of ‘Q’ = 20 years
