Question

Nelson says to his sister, “When I reach your age, you will be 35 years old.” His
sister says to Nelson, “When I was your age, you were only 2 years old.” How old
are Nelson and his sister?

Answer 1

Answer:

Nelson is 13 and his sister is 24

Step-by-step explanation:

Nelson can be no younger than 2, and his sister can be no older than 35. The difference between these two ages is 33. The key to this problem is finding the difference in ages between the two children. I got lucky and used 11 as the difference, or 33/3, and I added it to 2, one of the first ages referenced.
