Every single question in these two documents is from the Official GMATPrep Test database. These are clearly the best source of questions after the Official Guides. Just make sure you do these after you have taken the two Official Practice Tests in the GMATPrep software.

These are gmat prep questions unless he's mixed some questions from other sources. I've seen someone made a similar post before...

Ok but what about for instance the 5 question of the second dcument ??

Quote:
5. 354-!-item-!-187;#058&000214
If x, y, and z are integers, is x + y + 2z even?

(1) x + z is even.

(2) y + z is even.

This doesn't make much sense .....................

carcass,

Why? It is exactly the same as the question in the GMATPrep software. Is it because of the 2z there, because we know 2z is always even, so why did they put it there?

The question is really equivalent to Is x+y even?
Here each statement alone is insufficient.

1) x = 3, z = 3, y = 4 Answer is No
x = 2, z = 2, y = 4 Answer is Yes.
Insufficient.

same logic for statement 2 as well.

Now when we combine the two statements, do you see a clean way to do it that involves a simple step.
No paper or pencil required.

Cheers,
