(1) x = - y

(2) -x = -(-y)


Question: is x/y < 0?

Statement 1: x = - y

i.e. x/y = -1 (because given xy≠0)
SUFFICIENT

Statement 2: -x = -(- y)
i.e. x/y = -1 (because given xy≠0)
SUFFICIENT

Answer: Option D

Stmt 1: x/y = -1, Hence answer to is x/y <0 is Yes, hence suff.
Stmt 2: Rearrange to get x/y = -1, Hence answer to is x/y <0 is Yes, hence suff.

Hence Option D
