This question is written in a very confusing manner, since the answer seems to be x + y based on the wording

<sigh>

Glad I wasn't missing something on this. I couldn't figure out at all what this question is asking. Looks like x + y should be the answer, yet it's not among the choices. And it looks like x + y = 3x.
800 or bust!

(x-b)+b+(y-b)=3x, x+y-b=3x , therefore b=y-2x. Hence, the correct answer is B.
