x-y>10 is x-y > x+y ?
1 : 8-y > 10 so y < -2 since y is less than 0 x-y is always greater than 0 for all values of x
2: Similarly this is also sufficient so
IMO answer is D

2 : y = -20 ,y<0 , so suff

Hi all, new member here. Just want to point out the following: I read the question stem and translated the inequality x-y > x+y to -y > y , or in words "y is negative". Kind of makes it simpler and more concrete. After that point the answer is painfully obvious.
