    Question

    Present ages of P and Q are in the ratio 2:5

    respectively. If Q’s age, 15 years hence from now will be 5 times of P’s age, 5 years ago from now, then find the present age of Q.
    A 21 years Correct Answer Incorrect Answer
    B 24 years Correct Answer Incorrect Answer
    C 35 years Correct Answer Incorrect Answer
    D 40 years Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let the present ages of P and Q be 2x and 5x years respectively. According to the question, => (5x + 15) = 5 × (2x – 5) => 5x + 15 = 10x – 25 => 5x = 40 => x = 8 Therefore, the present age of Q = 5x = 40 years
