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
