Mastering Inequality Questions on the GMAT - Videos


Brian Galvin, Veritas Prep’s Director of Academic Programs, demonstrates how to smartly work with inequalities in GMAT Quant problems.



  1. how does that address the question stems individually? You skipped straight to the answer of E which I understand when combining both questions, but I do not understand the question stems separately.

  2. At 3:05, I don't understand… how did you get y>2? If you replace "y" by 2.1 then 2*2.1= 4.2 and therefore does not seems to be greater than 7 doesn't "y" has to be between 3.5 and 5 ? I'm not sure…
    Thanks you very much for the tip!

  3. If Y must be positive, and X cannot be either. It would be logically flawed to say that X can be negative if Y must be positive, because X multiplied by Y must be greater then 0. If Y is positive, and x is negative the answer is inherently negative and therefor less then 0.

    Thoughts? Not sure if this was supposed to work out this way for your example but I get the concept and strategy thanks.
