Question
The ratio of present age of A to that of B is 4:3 and
the ratio of present age of A to that of C is 4:5. The average present age of A, B and C is 24 years. Find the age of B, after 9 years.Solution
The ratio of present age of A, B and C = 4 : 3 : 5 (4x, 3x, 5x) The average present age of A, B and C = 24 years => (4x + 3x + 5x)/3 = 24 => 12x = 72 => x = 6 The age of B, after 9 years = 3 × 6 + 9 = 27 years
