No, such questions do not follow the accepted pattern on the official GMAT questions.

In GMAT data sufficiency questions, the two statements will never contradict each other. It is an unspoken rule on the GMAT that the value of the quantity being asked in the main stem will always be the same in case each statement alone is sufficient. This rule is not explicitly written in official GMAT sources, but is consistently seen in GMAT problems.

You will also see variations of the type listed below:

If x+y=6, then what is the value of x?

1) y^2 = 4
2) y=2

Here statement 1 is insufficient, and statement 2 alone is sufficient. But note that both statements share a common value of y. This is also a common scenario on data sufficiency questions.

Cheers,
Dabral

This is a dummy example but it demonstrate my question:

Question: What is the value of X?
1) X + 3 = 0 ->>> Sufficient
2) X + 5 = 6 ->>>> Sufficient as well

In this case, naturally I would choose E: because both are sufficient on it own
But the Dilema is: because they both produce different value, therefore, Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data specific to the problem are needed.

So which is E or N the correct answer? (Each or Neither?)

Thanks so you much!

The answer is D - each alone is sufficient.

Note that you should treat 1 and 2 as being completely independent of each other. Each can yield different values (although GMAT won't test you on such a technicality).

Only in the case that one doesn't suffice should you look at the combination of both.

What is important is - are you able to answer the question asked with the info provided? If so, great. They don't have to corroborate.

So, if each is independently sufficient, that takes priority and you shouldn't even consider what happens when you take them together.

Look above for the discussion.

For GMAT DS questions, if both statements are indeed sufficient individually, then they MUST give the same unique value.
