If y = −1/2, is 2x/y > 1?
(1) x < 0
(2) x is an integer
(1) x < 0
(2) x is an integer
2x/y = 2x/(-1/2) = -4x => is -4x >1 ?
St I
x < 0
if x = -1; -4x = 4 >1
if x = -1/8; -4x = 1/2 <1 -----------Insufficient
St II
x is an Integer
if x = -1; -4x = 4 >1
if x = 1; -4x = -4 <1 -----------Insufficient
St I and II
x < 0 and x is an Integer
if x=-1; -4x=4 >1
if x=-2; -4x=8 >1
if x=-100; -4x=400 >1
Hence Option C is correct.

If y = −1/2, is 2x/y > 1?
(1) x < 0
(2) x is an integer
(1) x < 0
(2) x is an integer
Using y, question is is -4x>1?
1) x<0. x could be -0.1, in which case -4x<1. Or, x could be -1, in which case -4x>1. Not suff.
2) Clearly insuff.
1)&2) Greatest value x can be is -1, in which case -4x>1. Suff. C
