Let the present ages of 'A' be 'm' years. Combined present ages of 'A' and 'B' = 25 + 27 = 52 years Present age of 'B' = (52 - m) years ATQ, (m + 4) = 0.6 X (52 - m + 8) Or, m + 4 = 36 - 0.6m Or, m + 0.6m = 36 - 4 So, 'm' = (32/1.6) = 20 Therefore, required age of 'D' = 1.45m + 3 = 1.45 X 20 + 3 = 32 years
