Data Sufficiency (DS) | Re: Is xy > 0? (1) x - y = 2 (2) (x/y) < 1

I) x-y=2

x=2+y
But we have no info about y so can't say anything about x also soInsufficient

II) x/y<1

2 cases
1) 4/5<1 both positive xy>0
2) any one is negative x/y<1 xy<0

Multiplecases-Insufficient

Combining both

(2+y)/y<1

2/y<0 so y<0

x=2+ y
If y is between -2 to 0 then x is positive and xy<0

If y is less than -2 then x is negative then xy>0

So Insufficient

Answer E

Give kudos if it helps
