    Solution

    ATQ,

    Let the present age of 'A' and 'B' be 6a years and 4a years respectively.

    So, age of 'A' 3 years ago = 6a - 3 years

    And, age of 'B' 8 years later = 4a + 8 years

    ATQ,

    6a - 3 + 4a + 8 = 50

    ⇒ 10a + 5 = 50

    ⇒ 10a = 45

    ⇒ a = 4.5

    Therefore, present age of 'A' = 6 × 4.5 = 27 years
