    A 8 years Correct Answer Incorrect Answer
    B 9 years Correct Answer Incorrect Answer
    C 10 years Correct Answer Incorrect Answer
    D 11 years Correct Answer Incorrect Answer
    E 12 years Correct Answer Incorrect Answer

    Solution

    Let the present age of ‘S’ be ‘x’ years
    Therefore, present age of ‘R’ = 1.3x years
    ATQ;
    (1.3x – 4) = 1.6 × (x – 4)
    Or, 1.3x – 4 = 1.6x – 6.4
    Or, 2.4 = 0.3x
    Or, x = 8
    Therefore, present age of ‘S’ = 8 years
