Inequality

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
