Statement (1) BY ITSELF is sufficient to answer the question, but statement (2) by itself is not. Statement (2) BY ITSELF is sufficient to answer the question, but statement (1) by itself is not. Statements (1) and (2) TAKEN TOGETHER are sufficient to answer the question, even though NEITHER statement BY ITSELF is sufficient. EITHER statement BY ITSELF is sufficient to answer the question. Statements (1) and (2) TAKEN TOGETHER are NOT sufficient to answer the question, requiring more data pertaining to the problem.
Let me know what you guys think and I will post the OA and OE. I have some questions on this.
Kudos me if you like this!
(1) X+Y is 5. Doesnt tell us much about X. It could be {0,1,2,3,4,5} (2) Result of rounding is 7.185 --> This means that X can be {5,6,7,8,9}
(1+2) Combining both, onlt possibility for X is 5.

There are serious problems with this question. Clearly the intended answer is C, but that would mean our number is 7.81450. There are two problems with this:
* if you have the number 7.81450, then you don't normally write the final zero; that number is 7.8145. A test taker could very reasonably assume that y is nonzero here and quite legitimately choose A as the answer.
* More importantly, you can't round the number 7.8145 to the 'nearest thousandth'; it's equally close to 7.814 and 7.815. Whether you round this to 7.814 or to 7.815 depends on which rounding conventions you are using, and those conventions are different in different contexts (in American education, children are often taught to round up in this case, but that is definitely *not* generally true in real mathematics). The GMAT will never ask about rounding off a number that is exactly halfway between two potential candidates -- you won't be asked to round 1.5 to the nearest integer, for example -- because depending how you learned rounding, you could give three different completely legitimate answers: 1, 2 or 'it can't be done'.
This is just a badly designed question.
Edit: I guess all of my issues with the question would be resolved if the number they asked about was something like "7.184XY4" instead of "7.184XY". If they add one nonzero digit after the 'Y', there's nothing wrong with the question.
