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 βAβ be βaβ years So, 3(a β 20) = a + 12 Or, 3a β 60 = a + 12 Or, 2a = 72 Or, a = 36 Present age of βBβ = 5/4 Γ {36 + 12} β 12 = 60 β 12 = 48 years Present age of βCβ = 38 Γ 3 β 36 β 48 = 30 years
