Most Basic DS query

Hi,

I know it sounds silly but I wanted to have the following two basic concepts confirmed. Please post your responses.

Question Type 1
-------------------
Find x.

Statement 1: x-5 = 10
Statement 2: x+2 = 9

Now, obviously statement 1 and 2 are independently sufficient to solve for x. But here is my doubt: Since the two statements are giving two different values of x; 15 and 7 respectively, should the answer be [D] or [E]?

Question Type 2
-------------------
In case of yes/no questions, if statement 1 results in 'YES' whereas statement 2 results in 'NO', should the answer be [D] or [E]?

I think it should be [D] in both the cases above. However I am confused by the Manhattan Number Properties book (page 82) where it mentions that "The two statements can not contradict each other".

Please clarify.

Simple answer to your question:

those two scenarios will NEVER arise on the GMAT.

On all GMAT DS questions, there has to be at least one solution in common between the two statements. A fundamental rule of DS is that it has to be possible for both statements to be simultaneously true.

So, the happy answer to your question is: don't worry about it!

:D
