    Question

    Present ages of P and Q are in the ratio 7:8

    respectively. If Q’s age, 8 years hence from now will be 2 times of P’s age, 5 years ago from now, then find the present age of Q.

    C 35 years Correct Answer Incorrect Answer
    D 36 years Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let the present ages of P and Q be 7x and 8x years respectively. According to the question, => (8x + 8) = 2 × (7x – 5) => 8x + 8 = 14x – 10 => 6x = 18 => x = 3 Therefore, the present age of Q = 8x = 24 years
