    D 18 yrs Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let present ages be:

    Karan = p

    Amit = q

    (p + 6) + (q + 6) = 70

    ⇒ p + q = 58 ——— (i)

    p - 15 = q - 15 - 12

    ⇒ p = q - 12 ——— (ii)

    (q - 12) + q = 58

    2q = 70

    q = 35

    Amit's age in 6 years = 35 + 6 = 41 years
