    Present age of ‘M’ is 25% more than that of ‘N’.

    5 years ago, ‘M’ was 1.5 times as old as ‘N’. Find the present age of ‘N’.
    A 8 years Correct Answer Incorrect Answer
    B 9 years Correct Answer Incorrect Answer
    C 10 years Correct Answer Incorrect Answer
    D 11 years Correct Answer Incorrect Answer

    Solution

    Let the present age of ‘N’ be ‘x’ years
    Therefore, present age of ‘M’ = 1.25x years
    ATQ;
    (1.25x – 5) = 1.5 × (x – 5)
    Or, 1.25x – 5 = 1.5x – 7.5
    Or, 2.5 = 0.25x
    Or, x = 10
    Therefore, present age of ‘N’ = 10 years
