Cary is 4 years older than dan. In 8 years the sum of their ages will be 64. Find the age of each man now.

Well, you take 4D+8=64. If you subtract 8 from each side, you will end up with 56. Now, the problem is 4D=56. You divide 4 on each side. It will be as so, D=14. (D is for Dan)

Now, you take Cary which will be C. You use 14 and add 4 to it. You will get 18.

Therefore, Cary must be 18 while Dan is only 14.

22 dan and 26 Cary years old
