    Present age of β€˜P’ is 50% more than that of β€˜Q’.

    6 years ago, β€˜P’ was twice as old as β€˜Q’. What is the present age of β€˜Q’?
    A 6 years Correct Answer Incorrect Answer
    B 10 years Correct Answer Incorrect Answer
    C 12 years Correct Answer Incorrect Answer
    D 14 years Correct Answer Incorrect Answer
    E 16 years Correct Answer Incorrect Answer

    Solution

    Let the present age of β€˜Q’ be β€˜x’ years
    Therefore, present age of β€˜P’ = 1.5x years
    ATQ;
    (1.5x – 6) = 2 Γ— (x – 6)
    Or, 1.5x – 6 = 2x – 12
    Or, 6 = 0.5x
    Or, x = 12
    Therefore, present age of β€˜Q’ = 12 years
