Q29. if X>1 and Y>1, is X<Y? (1) X^2/(XY+X)<1 (2) XY/Y^2-Y<1
A Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient
B Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient
C BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D EACH statement ALONE is sufficient E Statements (1) and (2) TOGETHER are NOT sufficient
这道题我做的时候选的是B,我理解的(2)是 XY/(Y^2-Y)<1
按这个式子解出来的答案对吗?
我看到还有的(2)是 (XY/Y^2)-Y<1
哪个才是原题呢?
求帮助^^
