I am going with A....

st1:
whatever value of Y, X is greater

st2:
if y=-1, x=0 (true)
if y=0, x=-2 (false)
if y=1, x=0 (false)

But looking at your post, I am afraid that I am going to be wrong... But I know that someone will reply soon with the correct logic. :lol:

Will go with A

1) X-Y = 2 Subsititute any value and u will see x > Y

2) Say y = -1, then x = -6, x<y
Say y = 4 then x = 4, x>y

Hence Insuff

Its A.

I did with a different method.

Stem is Is x-y> 0 ?

St1: x = y+2 i.e x-y = 2 : SUFF

St2: x/2 = y-1 i.e x-y = 2-3y. So 2-3y could be anything.: INSUFF

OA is A..

I figured out my mistake.. I thought it was D for some reason..

I did not consider a huge number like 10 when I was doing my calculations.!!!

Thanks guys!

(1) is suff, check for 6 = 4+2, 0 = -2+2, 2 = 0+2

(2) x = 2(y-1) -- can't say, for e.g. if = -2, then x = -6, but if y = 26 then x = 50.
