    Question

    Present ages of P and Q are in the ratio 4:7

    respectively. If Q’s age, 15 years hence from now will be 6 times of P’s age, 6 years ago from now, then find the present age of Q.
    A 21 years Correct Answer Incorrect Answer
    B 26 years Correct Answer Incorrect Answer
    C 35 years Correct Answer Incorrect Answer
    D 33 years Correct Answer Incorrect Answer

    Solution

    Let the present ages of P and Q be 4x and 7x years respectively. According to the question, => (7x + 15) = 6 × (4x – 6) => 7x + 15 = 24x – 36 => 17x = 51 => x = 3 Therefore, the present age of Q = 7x = 21 years
