from 1) x and y are either both positive and x>y or x and y have different signal and x> 0. more than 1 possible answer, insufficient.
from2) both x and y have the same signal negative or positive we don't know, insufficient
combining both, from 1) x is always positive and from 2) x and y both have the same signal, so both are positive. answer C

Can someone explain what happens after we combine both stmts? I'm still a little confused with agps's explanation. Thanks.

A suggestion when u find it diff to relate to variables plug in values.
Take the question in discussion -
Statement 1 gives X>Y
So X can be 6 and Y can be 3 or X can be -3 and Y can be -6
Statement 2 gives X/y >1
If you look at the statement alone again X can be 6 and Y can be 3 or X can be -3 and Y can be -6
But if you combine the statement you know X > y so for x/y to be > 1 they will have to be positive. IF they were negative X/y would be a fraction and so less than 1

Stmt 1 - both, x and y, can be positive or negative. NOT SUFF
Stmt 2 - both will be negative or positive. NOT SUFF
Together - from stmt 2 |x|>|y| and stmt 1 satisfies only when both are positive. So SUFF
Ans C
Stmt 2 - both will be negative or positive. NOT SUFF
Together - from stmt 2 |x|>|y| and stmt 1 satisfies only when both are positive. So SUFF
Ans C
