This one surprised me a little bit. I thought I'd need a lot of information given but as I wrote the facts down, it became apparent that the only two pieces of information needed are the sum and differences:

(1)
(2)
Add (1) to (2) to get:

Check:
We were told the 10's digit is twice the one-hundreds digit. 8 = 4*2 (ok)
Also:
481 - 184 = 297
481 + 184 = 665
