Is x > y?

Is x - y > 0

(1) x - y > 3:

x - y > 3 > 0. Sufficient.

(2) x + y > 3. The sum of two numbers is more than 3. We cannot say from this which one of the numbers is greater. Not sufficient.

Answer: A.

Statement 1 says x-y> 3 i.e positive nbr. This means x should be greater than Y else the result will be negative. So sufficient. For Statement 2 x + y>3 , we will not be able to figure which is greater so not sufficient. So answer A

Question: Is x > y ?

or Is x - y > 0 ?

St 1: x - y > 3 -------Clearly sufficient

St 2: x + y > 3

If x = 2 and y = 2, we have 2 + 2 > 3, AND answer to the question is NO.

If x = 5 and y = 2, we have 5 + 2 > 3, AND answer to the question is YES. Insufficient

Hence (A)
