Let the present age of 'A' and 'B' be '5m' and '7m' years respectively. So, 5m + 7m = 48 Or, 12m = 48 Or, 'm' = 4 Present age of 'A' = '5m' = 5 X 4 = 20 years Present age of 'B' = '7m' = 7 X 4 = 28 years ATQ, 20 + n = 28 - n Or, 2n = 8 So, 'n' = 4 Therefore, present age of 'C' = 20 - (3 X 4 - 4) = 20 - 8 = 12 years
