than B. The ratio of age of A, 7 years hence and age of B, 6 years ago is 3:2. What was age of C, 11 years ago?Solution
Let the present age of B be x years. Aβs present age = (x + 4) years Cβs present age = (x - 5) years According to question, => [(x + 4) + 7]/(x -6) = 3/2 => x = 40 Cβs age, 11 years ago = (40 - 5) β 11 = 24 years
