Six years ago, the ratio of the ages of A and B was 4:1. Two years from now, the average age of A and B will be 33 years. Find the present age of A.

1. 16
2. 42
3. 48
4. 46

Correct answer: 46

Solution

Two years from now, the average age will be 33, so their total age then will be 66. Hence, their present total age is 62. Using the ratio six years ago, the ages were 4x and x, and after adding 6 years each, the present ages satisfy the total 62, giving A = 46.
