We noticed you are actually not timing your practice. Click the START button first next time you use the timer.
There are many benefits to timing your practice, including:

(1) x-y = 1/2, can't say if both are +ve (for e.g. 2,-1.5 or -1.5, -2) (INSUFF)
(2) x/y > 1 ; {-10, -5} or {10,5}. even combining both does not provide a definite answer.

(1) x-y = 1/2, can't say if both are +ve (for e.g. 2,-1.5 or -1.5, -2) (INSUFF) (2) x/y > 1 ; {-10, -5} or {10,5}. even combining both does not provide a definite answer.

(E)

(1) says x > y
(2) says x and y are either both +ve or both -ve.

considering both together,
if x > y, then both need to be +ve to satisfy x/y > 1

The answer clearly is C
(1) said that x>y
(2) said that x/y>1 so x,y must be both positive(x>y) or negative (x<y)
(1),(2) together we have x,y are both positive numbers.

well...DONT do anything like cross multiplication cause we dont know the signs of x or y. All we know is that X and Y have to have the same sign + or -ve. Insuff

lets take em together

sub vaule for x

1/2y + 1 > 1; well this can only be true if Y is +ve...if Y is +ve then X is +ve (given in statement 2)..

C it is....

Hope this helps..its a very simple way of lookin at this problem..and time efficient too, since i dont have to plug in numbers...
