I'd go E almost instantly.
If p = q = .1, x is not integer
If p = q = 1, x is integer

1) x=3p-2q
2) p=q
(1) not sufficient. P and Q could be fractions, and the operation of x could result in some fraction as well.
(2) not sufficient. Same reason as above.
(1) and (2) put together doesn't tell us anything more than we already know.
So (E).

I would choose E too.
p and q could be fractions like p = 1/2 and q = 5/7 or they both could be integers.

Alex

actually this is from one of the paper tests and it gives the answer as A which makes no sense to me.

nope, E. Definately. The best we can get to is combining them together and seeing that x = p = q. But since we don't know what they are, just that their not zero, it's got to be E.
