Like Bunuel already mentioned - remainder questions on the GMAT exclusively deal with positive numbers only.
Still, the way we need to solve such a question is always remember that the remainder when dividing by |x| is always between 0 and X-1 (Inclusive) i.e remainder is always positive. ( By definition)
-12 = -5(n) + R
-12 = -5(3) + R
R = 15 - 12 = 3
Hence the remainder will be 3.
Or in other words, if you get a remainder of -2 ( which you will if you put n = 2 above) remember to arrive at 5 - 2 = 3 such that the remainder is always
positive non-negative.
Hope this helps.

Bunuel Gladiator59Shouldn't it be D .
Because it says what number so it shuld 12 / 5 rem= 2 How E cause it does't says multiple of -5
other wise 15 -12 then rem = 3 would be possible Still confunsed
