Question
In 12 years, 'A's age will be three times what it was 20
years ago. After 12 years, the age ratio between 'A' and 'B' will be 4:5. Currently, the average age of 'A', 'B', and 'C' together is 38 years. Determine the present age of 'C'.Solution
Let present age of ‘A’ be ‘a’ years So, 3(a – 20) = a + 12 Or, 3a – 60 = a + 12 Or, 2a = 72 Or, a = 36 Present age of ‘B’ = 5/4 × {36 + 12} – 12 = 60 – 12 = 48 years Present age of ‘C’ = 38 × 3 – 36 – 48 = 30 years
