    Present age of тАШMтАЩ is 25% more than that of тАШNтАЩ.

    4 years ago, тАШMтАЩ was 1.5 times as old as тАШNтАЩ. What is the present age of тАШNтАЩ?
    A 8 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

    Solution

    Let the present age of тАШNтАЩ be тАШxтАЩ years
    Therefore, present age of тАШMтАЩ = 1.25x years
    ATQ;
    (1.25x тАУ 4) = 1.5 ├Ч (x тАУ 4)
    Or, 1.25x тАУ 4 = 1.5x тАУ 6
    Or, 2 = 0.25x
    Or, x = 8
    Therefore, present age of тАШNтАЩ = 8 years
