    D 55 yrs Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let the present age of Nitin = y years

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

    According to the question,

    (y - 4):(60 - y - 4) = 6:7

    β‡’ 7(y - 4) = 6(56 - y)

    β‡’ 7y - 28 = 336 - 6y

    β‡’ 13y = 364

    β‡’ y = 364 Γ· 13 = 28

    So, present age of Sumit = 60 - 28 = 32 years
