Another NDB IMC Question

This makes no sense to me:

18) You are heading 280, with the NDB on a relative bearing of 160. If the variation is 5 degrees west, what is your true bearing from the NDB?
A 080
B 075
C 255
D 260
You chose D, but the correct answer was C.

I completely guessed this. My working was:

1. Bearing to beacon = my bearing + NDB = 280 + 160 = 540 (180) degrees to the beacon
2. Variation west, compass best = 180M = 175T TO bearing
3. Bearing FROM the NDB = add 180 = 355T bearing

Which is COMPLETELY wrong! I've obviously done something extremely obviously wrong! I thought I had (1) absolutely correct but it's obvious I'm making a mistake there.
