j for older broth
b for brother
Each starts as j=20 and b=8.
Some number of years pass, y. At that time, their ages become:
20+y for older brother (John)
8+y for brother (Jim)
, the question.
This will not happen going forward in time.
John is already 2.5 times older than Jim. The ratio will only decrease as y increases.
