GMAT NP + Inequality

by abhi75 » Tue Jun 17, 2008 6:51 am
If x > 1 and y > 1, is X < Y
1) x^2/(xy + x) < 1
2) xy/y^2-y < 1

The OA is E but the way I solved it I ended with a B. Can someone please point out the mistake.

From 1) x^2/x(y+1) <1> x < y+1 (This is not sufficient)
Answer is B, C or E.

From 2) x <y> 1, this should be sufficient. Is there any case where its not.

Thanks.
-A

Just a correction of the typo

From 2) x < y -1 and not X <Y> 1.

I am also getting B as the answer. Anyone who can explain how E can be the answer?
Good Luck
