A number $$ P $$ varies directly as $$ q $$ and partly inversety as $$ q^{2} $$. Given that $$ P=11 $$ when $$ q=2 $$ and $$ P=25.16 $$ when $$ q=5 $$, calculate the value of $$ P $$ when $$ q=7 $$.

When $$ q = 7 $$, $$ P $$ is approximately 35.08.

A number \( P \) varies directly as \( q \) and partly inversety as \( q^{2} \). Given that \( P=11 \) when \( q=2 \) and \( P=25.16 \) when \( q=5 \), calculate the value of \( P \) when \( q=7 \).
