I got a DS question aksing for the value of a variable x. The correct answer is D, each statement alone is sufficient.
But now the problem: I get different values from the two statements, e.g.: statement 1 -> x=3, statement 2 -> x=4.
Is that possible in DS questions?
This is how I like to explain why the two statements cannot give you conflicting answers:
Imagine that the GMAT DS question stem is a puzzle. You cannot answer it with the data given in the stem. So you get a clue (stmnt 1). You try and solve it using stmnt 1. Say, it is not enough. You get another clue (stmnt 2). You try and solve it using 2 alone. If it is not enough, you try solving using both statements. There is only one answer to the puzzle. The 2 statements are just 2 clues to the puzzle so it will not happen that they give conflicting answers.
