Are positive integers p and q both greater than n?
1) p - q > n
2) q > p
Can we solve this by adding the inequalities?

Adding inequalties is a good way to solve in general.
For this prob if u consider both statements together
substituting would be a good way to solve also
We know p-q>n and q>p and we are given p and q are both positive
p > q+n
q>p
therefore q > q+n
0>n
n is negative so p, q each are greater than n
Choose C
