Q29.

if X>1 and Y>1, is X<Y?

(1) X^2/(XY+X)<1  

Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient

l        Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient

l        BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

l        EACH statement ALONE is sufficient

l        Statements (1) and (2) TOGETHER are NOT sufficient

答案是E，但是我觉得应该是B

答案是E，但是我觉得应该是B

大家的意见呢？

(2) XY/Y^2-Y<1

这个化简到X-Y<Y^2
根据这个条件，X-Y既可以大于0也可以小于0

如果是X-Y>Y^2 （>0）就可以推出X>Y
