Rephrased question
Is x + s > r + y?

Statement 1:
Given x > r and s > y
Add both of them x + s > r + y

Statement 2:
If you notice carefully, this is a specific instance of generic case mentioned in statement 1.
So this can also answer the question.

(2) y = 2, s = 3, r = 5, and x = 6.

question : x – y > r – s=?
(x –r)+( s-y)>0

(1) is suffi since x-r >0 and s-y >0
(2)values given hence SUFFI

IMO D

First clarification... (x-y) is simply that.. x-y or is it |x-y|...

going with x-y then the answer still stays the same.. D no?

B.

if r-s =0 (x – y) / (r – s) > 1 ---> undefined

its x-y ....

and i dont think it'll be D (even if i add that "r is not equal to s" to take care of undefined issue)
Hint : 2 > -4 does not mean that 2/-4 > 1
