If ben is 5 years older than Tim four years ago, the ratio of the ages 7:6 find their present age Let Tim's age be T Then Ben's is T + 5 Four years ago, Ben was and always will be 5 years older that Tim Four years ago, Tim and Ben were T - 4, and T + 5 - 4, or T + 1, respectively We then get:7(T - 4) = 6(T + 1) ----- Cross-multiplying 7T - 28 = 6T + 6 7T - 6T = 6 + 28 Tim's age, or T = 34 Add 5 to Tim's age to get Ben's.
