Question stem:
Is x/y > x/(y+1) ?

If x = 0, the two sides are equal.

Otherwise, there are three cases to consider:
1)For y>0; is x>0 ?
2)For y<-1; is x>0 ?
3)For -1<y<0; is x<0 ?

First statement:
x does not equal zero; we know that the two are not equal, but that's all.
Not sufficient.

Second statement:
x>y; x and y can both be negative or positive, or y is negative and x is zero or positive.
Not sufficient.

Both statements:
Not sufficient.

Answer is E.
