(1) 6 – y is a positive integer.
(2) 6 + y > 7.2


St I
for 6 – y to be a positive integer, 6 > y which means 7 > y ---------Sufficient

St II
6 + y > 7.2
y can be 2 or 3 or 4 or any positive integer > 2 ------------Insufficient

Hence option A is correct
Hit Kudos if you liked 8-)

(1) 6 – y is a positive integer.

If 6 - y is a positive integer. Then y has to be an integer from 5 to lower. Therefore, 1 is sufficient.


(2) 6 + y > 7.2
Insufficient

Therefore, answer is A

(1) 6 – y is a positive integer.

Y could be negative thus making the solution a positive integer - therefore A is insufficient.

(2) 6 + y > 7.2

Y can be anything over 1.2 - to infinity. But with statement 1, in which the positive range of Y is between 0 and 5, we can conclude that Y < 7. Therefore - C.
