ATQ, Let the present age of Neha be 'n' years. Neha's father's age = (6n + 4) years Neha's mother's age = (6n + 4) - 8 = (6n - 4) years ATQ: (6n + 4) : (6n - 4) = 25 : 23 Or, 23 × (6n + 4) = 25 × (6n - 4) Or, 138n + 92 = 150n - 100 Or, 12n = 192 Or, 'n' = 16 Present age of Neha's father = 6 × 16 + 4 = 100 years Present age of Ria = 16 - 3 = 13 years Required sum = (100 - 5) + (13 - 5) = 95 + 8 = 103 years
