    C 36 years Correct Answer Incorrect Answer
    D 60 years Correct Answer Incorrect Answer
    E 48 years Correct Answer Incorrect Answer

    Solution

    Let the age of son be x Father’s age = 4x Wife’s age = 4x– 12 Daughter’s age = x+ 8 According to question, Daughter’s age = `1/2` mother’s age (x+ 8) = `1/2` × (4x– 12) 2x+ 16 = 4x– 12 2x= 28 x = 14 Father’s age = 4x= 4 × 14 = 56 years Wife’s age = 4x– 12 = 56 – 12 = 44 years Daughter’s age = 14 + 8 = 22 years
