inequality

by ketkoag » Tue Mar 31, 2009 10:14 am
if X>1 and Y>1, is X<Y?
(1) X^2/(XY+X)<1
(2) XY/Y^2-Y<1

OA: E
My ans: B coz by statement 2 we get x/(y-1) < 1
=> y> x + 1
since x> 1 and y > x + 1
y> x hence sufficient.
please lemme know if its wrong.

S1 isn't SUFF. in the equation x < y +1, if x = 3 then y could also equal 3 because 3 < 3 +1 (INSUFF)

similar structure in S2. so my answer would be E
**remember, both x & y are positive numbers**

ketkoag, looks like your online question set has been puzzling quite a few people :) doesnt seem like a reliable one.
