100A + 10B + C + 100A + 10C + B = 100C + 10B + A
200A + 11B + 11C = 100C + 10B + A
199A + B = 89C

A=4, C=9
199(4) + B = 89(9)
796 + B = 801
B=5

ABC + ACB = CBA
459 + 495 = 954

Solution 2 will wait until later.

Good Title, "Revenge of the Brain Teaser" parallel to "Revenge of the Sith Teaser" where the "Sith Teaser" is one of Astro's Scandinavian Nymphos.

What?

Ah yes, I'm with Shok Tinoktin on this. He beat me to it.
