    Six years from now, P’s age

    will be 50% greater than his age two years ago. The current age ratio of P to Q is 6:7. How many years from now will Q celebrate his 30th birthday?
    A 20 yrs Correct Answer Incorrect Answer
    B 10 yrs Correct Answer Incorrect Answer
    C 9 yrs Correct Answer Incorrect Answer
    D 18 yrs Correct Answer Incorrect Answer

    Solution

    ATQ, Let the present age of P = ‘y’ years Then, ATQ (y + 6) = 1.5 × (y – 2) Or, y + 6 = 1.5y – 3 Or, 0.5y = 9 So, y = 9 ÷ 0.5 = 18 So, present age of Q = 18 × (7/6) = 21 years So, Q will celebrate his 30th birthday 9 years later i.e. (30 – 21) = 9 years
