1) P - Q > n

2) Q > P


C

(1)
Say P=5, Q=1, n=3, then both are NOT greater than n
Say P=5, Q=1, n=0, then both ARE greater than n
INSUFFICIENT

(2) Don't know n
INSUFFICIENT

Together, add them up
P - Q > n
Q > P
is P - Q + Q > P + n
n < 0
Because both P and Q are positive, they must be greater than n
SUFFICIENT

C

statement 1: Insuff
n = 0
p = 10
q = 1
10 - 1 > 0

n = 5
p = 10
q = 4
10 - 4 > 5

statement 2: insuff, no relationship between q and n or p and n

Together
since p and q are positive integers, and q is greater than p, the result of p - q is a negative integer that is greater than n, therefore n must be a negative number.
