请教gwd-25-29

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

Answer :e

请教这题的答案是不是有误啊，B是充分的。XY/Y^2-Y<1----〉X+1<Y

Are you sure it's XY/(Y^2-Y), not (XY/Y^2)-Y ?

ETS is so tricky!

理解为(XY/Y^2)-Y<1=〉x/y-y<1=>x/y<y+1=>x<y(y+1)

因为y>1，则x<y(y+1)<y

还是应该选B

如果认为是(XY/Y^2)-Y的话，答案就为E  

但是，真实考试的时候也会这样显示么？那怎么分辨它是什么意思啊？
