    C 45 years Correct Answer Incorrect Answer
    D 40 years Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let the present age of Sourav is x years. Therefore, present age of Rishav is x + 0.25x = 1.25x years According to the question, (x + 8): (1.25x + 8) = 5:6 Or, 6x + 48 = 6.25x + 40 Or, 0.25x = 8 Or, x = 32 years Therefore, present age of Rishav = 1.25x = 1.25 × 32 = 40 years Age of Rishav after 10 years = 40 + 10 = 50 years
