    A 45 yrs Correct Answer Incorrect Answer
    B 35 yrs Correct Answer Incorrect Answer
    C 65 yrs Correct Answer Incorrect Answer
    D 55 yrs Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let the present age of Sohan = y years

    Then, present age of Rohan = (60 - y) years

    According to the question,

    (y - 5):(60 - y - 5) = 2:3

    ⇒ 3(y - 5) = 2(55 - y)

    ⇒ 3y - 15 = 110 - 2y

    ⇒ 5y = 125

    ⇒ y = 125 ÷ 5 = 25

    So, present age of Rohan = 60 - 25 = 35 years
