The GRE questions posed during the test are conceived to be solved in a certain amount of time and usually without calculator.

Nonetheless, you do have during your official exam.

Let the principal amount is P. In here we have used the multiplier concept for compounding quarterly.
So, 12000=p(1+8%/4)^(3*4) or, p ~ 9500
So A is the answer.

you did not turn 8/4 into percent form, it's 8/4/100

Notice how this is not a perfect question, in fact, it is not an official question.

An official question has perfectly all the answer choices in ascending order. So the answer , that is A, should be in the second place. Therefore, B.

Aside from this consideration the question is pretty straightforward if you use the answer choices.

start with B

9,326 *1.08=10,072

this value per 1.08 another two times (3 in total) and you will get a result a bit far from 12,000

At this point is reasonable to think the answer is A which is slightly higher as value
