Are positive integers p and q both greater than n?

(1) p-q is greater than n
(2) q>p

OPEN DISCUSSION OF THIS QUESTION IS HERE: http://gmatclub.com/forum/are-positive- ... 29425.html

Whether following approach is wrong?
1) p-q>n
p>n+q, so p greater than n, but can not be decided whether q > n. Insufficient.
2) q > p, no information about n. so insufficient.

For C
q>p and p>n so, p and q both are greater than n.

If wrong please help.

Whether following approach is wrong?
1) p-q>n
p>n+q, so p greater than n, but can not be decided whether q > n. Insufficient.
2) q > p, no information about n. so insufficient.

For C
q>p and p>n so, p and q both are greater than n.

If wrong please help.


Given: \(p=integer>0\) and \(q=integer>0\). Question: is \(p>n\) and \(q>n\)?

(1) \(p-q>n\). Clearly insufficient.

(2) \(q>p\), no info about \(n\). Not sufficient.

(1)+(2) Sum (1) and (2) (we can safely do this as their signs are in the same direction): \(p-q+q>n+p\) --> \(n<0\). As given that both \(p\) and \(q\) are positive then they are greater than negative \(n\). Sufficient.

Answer: C.
