should be A-33.

Just do 100/3. for every three numbers there is a 3 multiple.

What do you say about the total number of integers between 99 and 199 that are divisible by 3?

Including the boundaries? Obviously need to consider two things in such situations - boundaries, and rounding.

Yes, it is a GMAT trap. I use always a formula:

N=\frac{Ne-Nb}{d}+1

100..200: N=\frac{198-102}{3}+1=33

99..199: N=\frac{198-99}{3}+1=34
