What is the value of y? - Need help

by Max1110 » Tue Aug 28, 2012 7:57 am
Hello there,
I am preparing for the GMAT test and right now everything looks good. Unfortunately I stumbled over an issue regarding the following type of Question in the Data Sufficiency Section in the Cracking the GMAT book.

What is the value of y?
(1) y is an even integer such that -1.5 < y < 1.5
(2) For any integer a =/ 0, ay =0

The answer would be D since in both statements the answer would be 0 for both statements. This sounds completely logical to me but what if the change the question a bit:

What is the value of y?
(1) y is an even integer such that 1.5 < y < 2.5
(2) For any integer a =/ 0, ay =0

Would the answer still be D? The results for both statements would be different but both (Statement 1 = 2, Statement 2 = 0) can be solved on their own and therefore are alone sufficient.

Thank you if somebody could help me sort it out :)

Max

GMAT will never pose questions where statement 1 and statement 2 are both individually sufficient but give a different answer to the question -Period-

For the second version of the problem you have stated, Statement 1 will no longer be sufficient. If y is an even integer in the range -1.5<y<2.5, then y can be O or 2. In which case only statement 2 will be sufficient and the answer will be B.

IMO D for the first question
IMO B for second question
