Are positive integers P and Q both greater than N?

Are positive integers P and Q both greater than N?

(1) P-Q is greater than N
(2) Q>P

Using Stmt 1)

P – Q >  N….we can infer P > N, but we have no info on Q. Can Q be less than N ?

Ex

P            Q               N

5            1                2

5            3                1

Insuff.

Using Stmt 2)

Q>P

But does no provide any information on N.

Insuff

Together :

Q > P > N….. Suff.

takeaway:
you can ADD TWO INEQUALITIES TOGETHER if the inequalities are BOTH "<" OR BOTH ">".

-q>n-p
+
q>p
_________
0>n
