I'd say it's E.
(1) x<y doesn't say anything about z
let's take x=-2, y= 3, z= 1 => 1>0 true
x=2, y=3, z= -3 => 1>0 true
Not suff

(2) z<0, doesn't say anything about x and y
not suff

(1)(2) x<y, z<0
x=-1, z = -1, y=1 => -2<0 true
x=1, z = -1, y=2 => -1<0 true
Not suff

1) x < y
2) z < 0


Given (x+y)/z> 0 there are only two combinations possible

1) (X+Y)<0 ;z<0
2)(X+Y)>0 ; z>0

S1 = only gives information about relationship betn x and y , insuff
S2 = no info about x and y so insuff

combining two , we know for sure (X+Y) must be less than 0 , and since x<y per S1, x has to be less than 0 , so I would go for answer C

any comments?

Sod, are you saying its E for (X+Y)/z

I had a typo with the brackets in the original, but just fixed it.
