i've heard before that if an answer choice is very close, but not exact, it is most often wrong - or if the answer is partly wrong, it is entirely wrong.

below is a question from one of the old/retired official question where the given answer (1000) is not the exact answer (990).
1. am i doing something wrong?
2. it doesn't seem to be an approximation problem, since one of the choices (1210) is not rounded off to the nearest hundred.
do these sort of questions still appear?
3. if so, is it best to pick the closest answer like above?

------------
8. If a 10 percent deposit that has been paid toward the purchase of a certain product is $110, how much more remains to he paid?
(A) $880
(B) $900
(C) $1,000
(D) $1,100
(E) $1,210

The question is what is the amount left to be paid after the first deposit..With the 10% deposit amount it can be deducted that the original amount is 1100..And when you deduct 110 from 1100 we get an answer of 990 which is closest to answer choice C ( 1000 )..This is the best among the other choices because it is the closest approximation..So you are not wrong and your approach is right..
