Answer 1

12 and 93.

Explanation:

Let the grandsons age be x then Mr. Roger's age = 8x - 3.

Five years ago the grandson's age was x-5 and Mr Rogers was 8x - 8 years old , so:

8x - 8 - (x - 5) = 81

8x - 8 - x + 5 = 81

7x = 81 + 8 - 5 = 84

x = 12.

So the grandson is 12 and Mt Rogers is 8*12 - 3 = 93.
