Question
Four years ago from now age of 'A' was 16 years. 'B' is
8 years younger than 'A'. After how many years from now, ratio of age of 'A' and 'B' will be 7:5 respectively?Solution
Present age of 'A' = 16 + 4 = 20 yearsPresent age of 'B' = 20 - 8 = 12 yearsLet the required time be 'n' years.So, (20 + n) :(12 + n) = 7:5Or, 5 X (20 + n) = 7 X (12 + n)Or, 100 + 5n = 84 + 7nOr, 2n = 16Or, 'n' = 8
