0 is an integer, neither positive nor negative. What else do I need to know about 0?

Is 0/2 undefined for GMAT and I don't have to worry about using 0 for plugging-in?

Here's the DS:

If p and q are integers, is (p + q) / 2 an integer?

1) p < 17
2) p = q

I picked E because I plugged in 0 in s2 but the correct answer is B.

Thanks!

Hi,

0/ (any number) =0

So even though u put '0' in st2 then it becomes 0, an integer.

Yep, answer is B. In case you want to see the approach...

The question is basically asking "Is p+q even?". For it to be even, both p and q have to be odd or both have to be even. Zero is an even integer, by the way.

(1) Just pick numbers...if p=16 and q=3, then (p+q)/2 is not an integer. But if you pick p=16 and q=2, then (p+q)/2 is an integer. Or you could just use the rephrasing of the question I mentioned above and you'll know right away it's insufficient.

(2) If p=q, then (p+q)/2 is just equal to 2p/2, or 2q/2. In either case, you get p or q, both of which are integers. So it is sufficient.

1) p < 17
2) p = q

(p + q) / 2 will be an intiger only if p+q= even ie : even + even or odd+odd

from one p could be either or odd or even and no data about q....insuff

from two

p = q thus both can be even ( 0 is even) or both are odd

thus p+q / 2 is even intiger.....suff

mY answer is B
