    Present age of β€˜P’ is 60% more than that of β€˜Q’.

    8 years ago, β€˜P’ was twice as old as β€˜Q’. Find the present age of β€˜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 β€˜Q’ be β€˜x’ years
    Therefore, present age of β€˜P’ = 1.6x years
    ATQ;
    (1.6x – 8) = 2 Γ— (x – 8)
    Or, 1.6x – 8 = 2x – 16
    Or, 8 = 0.4x
    Or, x = 20
    Therefore, present age of β€˜Q’ = 20 years
