I am little confused on somethings in DS sorry if it's wrong area to post.
1) what if one is able to solve DS question without needing the statements? I mean if question could be solved with given data of the question itself then is it D or E?
2) in inequalities if the question is "is X negative?" if by statement i) we get X = 0 or X>0 and statement ii) gives us X>0 or X<0. - - - - does it mean answer is "C" as I pick X>0 from both. Or it's. E?

In a valid GMAT question, this will never happen. If it happens to you, then one of two things has happened:
- you've made a mistake while solving the problem - check your work!
- you're solving a bad problem (most likely one that somebody made up, not an official GMAT problem.)

You should always work with one statement at a time first, before you try putting them together.

The first statement is sufficient, since it tells you that x definitely isn't negative.

The second statement isn't sufficient, since it doesn't tell you for sure whether x is or isn't negative.

If the first statement is sufficient, and the second one isn't sufficient, the answer has to be (A).
