E.

Les assume that X/Y > X/(Y+1)
The value of this expression depends upon the sign of X because the denominator is always increasing.
If X is +ve this is true but if X is -ve then this is false.

Stmt 1.
No clue abt. sign of X. So insuff.

Stmt 2.
No clue abt. sign of X.

Combining also does not tell anything abt. the sign of X.Hence insuff.
----------------------------------------------------

Using numbers,
X=6 and Y=2.
6/2 > 6/(2+1)
If X= -6 and Y = 2
-6/2 < -6/(2+1)
