What percent of the positive value of p is the positive value of q?
(1) \(\frac{p + q}{p − q} = 7\)
(2) \(\frac{p + q}{p − q} + \frac{p − q}{p + q} = 7 \frac{1}{7}\)

Basically we need\(\frac{p}{q}\)
(1)\(\frac{p + q}{p − q} = 7\) -> allows us to get the ratio , hence Suff.
(2)\(\frac{p + q}{p − q} + \frac{p − q}{p + q} = 7 \frac{1}{7}\) -> After simplification we get\(9.5q^2=5.5p^2\) also allows us to get the ratio -
hence Suff.
