1/p > r /r^2 +2
the question is asking:
r^2 +2 > pr ??
From stmt 1 we know:
r^2 +2 > r^2 ..so why s the answer not A

Hi
You are making classic mistake of assuming p > 0 when working with this inequality.
1/p > r /r^2 +2
the question is asking:
r^2 +2 > pr ?? ----> Only if p > 0 if p < 0 then r^2 + 2 < pr.. When you cross multiply for inequalities the inequality sign remains as it is when +ve and reverses when you cross multiply with -ve number
