DS: are the solutions to both statements always the same?

by wayofjungle » Fri Mar 11, 2011 11:13 am
Just wondering, if the solution to both DS statements after doing the math should match. In other words, if each statement is asking to solve an equation, will the solution to the equation be the same (ie. 5) or on a yes/no DS question, if statement 1 can sufficiently answer "no" than statement 2 (if sufficient) will also answer "no" never "yes".

I have found consistency that what I have stated is true, however before I develop this into a strategy, will somebody please confirm this? I have finished Princeton Review book with no mention of this. Thanks!

Yes, the statements of DS problems will never contradict each other. For example, if the DS prob were "Is X even" you will never find a problem where one statement tells you X is even, and the other one tells you X is odd.

Thanks. I realize I should have posted this in the Math Forum. Sorry about that, it wont happen again.

By the way, the strategy I have found by knowing this information may increase the success of "plugging in the solutions", by using it in data sufficiency questions. For example, when you know the solution to the first DS statement, you may be able to solve the second statement and confirm its sufficiency and save substantial time.

Thanks for switching forums. I just found this tip in the beatthegmat flashcards so heed my suggestion with much caution.

Common Trap
Do NOT use the information in one statement as an assumption in the second statement.
"¢ Statements are not necessarily related. "¢ View separately!
