Are x and y both positive?
1) 2x-2y = 1
2) x/y >1

Statement 1 can have two possibilities. x=-1.5 and y= -1 OR x=1 and y=1.5. When plugged into Statement 1 they both yield 1. So x and y could be both positive or negative. Not sufficient.

2) x & y can be both either positive or negative. -4/-2=2 >1 and 3/1 =3 >1. Not sufficient

Together these are not sufficient either.....so my answer is E

Good Question !!
Answer B

Stmt 1 x-y= 1/2 Insuff

Stmt 2 x/y > 1
From this stmt we know x > y and since x > y , x and y could only be both +ve .
It cannot be both -ve because x/y > 1 would not hold true.
