Is there any shorter way of doing this question beside plugging in the values?
Q.) If x is not equal to -y, is (x-y)/(x+y) > 1 ?
1) x>0
2) y<0
Q.) If x is not equal to -y, is (x-y)/(x+y) > 1 ?
1) x>0
2) y<0
Plugging in values is extremely efficient if you try combinations that satisfy both statements.akshatgupta87 wrote:Is there any shorter way of doing this question beside plugging in the values?

Let x=2 and y=-1.
Is (2-(-1)) / (2+(-1)) > 1? Yes.
Let x=1 and y=-2.
Is (1-(-2)) / (1+(-2)) > 1? No.
Since the combinations above satisfy both statements, and in the first case the answer is Yes and in the second case the answer is No, the correct answer is E.
