Question
A is 3 years older than B while C is 4 years younger
than B. The ratio of age of A, 8 years hence and age of B, 6 years ago is 5:4. What was age of C, 12 years ago?Solution
Let the present age of B be x years. Aโs present age = (x + 3) years Cโs present age = (x - 4) years According to question, => [(x + 3) + 8]/(x -6) = 5/4 => x = 74 Cโs age, 12 years ago = (74 - 4) โ 12 = 58 years
