Ann is 6 years old. Her brother Tom is now two times older. What will be the sum of their ages 10 years later?
Step-by-step reasoning process below:
38
Tom is currently two times older than Ann, which means he is 6 * 2 = 12 years old.

In ten years Ann is going to be 6 + 10 = 16 years old.

And Tom is going to be 12 + 10 = 22 years old.

So the sum of their ages will be 16 + 22 = 38.

.

The final answer: 38
