 |10y-4| > 7 AND y < 1Condition #1 Condition #2(10y-4) > 7 OR (10y-4) < -710y > 11 10y < -3 y > 11/10 y < -3/10The statement indicatates that Y < 1. Therefore Condition #1 can be excluded. Condition #2 says y < -3/10.From the answer choices you provided, only "A" satisfies this criteria.

 for solving inequalities like these you may want to visit a website that prepares you just for that. http://www.lofoya.com/Aptitude-Questions-And-Answers/Algebra/intro.htmMy comment may be moved into spam but this link is genuine and surely helpful.

 i'll leave it up. although you refer to an outside website (and keep in mind MGMAT does not endorse a website just because it shows up on our forums), this isn't technically spam because it may actually help someone. thanks for the link.. _________________Tim SandersManhattan GMAT Instructor
