Formula to solve multiple scenarios with one general outcome

I have an excel spread sheet where I need multiple outcomes for different scenarios.
I need to have the Disc to display a value based on 2 rows
example if e2=RRS then J2=50 but if e2 is blank I need the value to be based on the number of years
1-5 years 50
6-10 years 100
11-15 years 150
20+years 200

I was able to put the "if" formula for the first scenario but got stuck after that I tried an array formula still could not get what I wanted.
Please help
