Find the mean proportion between p−qp+qand(pq)2p2−q2{{p-q}\over {p+q}}and {{(pq)^2}\over {p^2-q^2}}.

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. pqp+q{pq}\over {p+q}.

p−qp+qand(pq)2p2−q2\frac{p - q}{p + q} \quad \text{and} \quad \frac{(pq)^2}{p^2 - q^2}

Mean proportion = ((p−q)/(p+q)​)⋅(pq)2/(p2−q2​)\sqrt{ ((p − q)/(p + q)​)⋅(pq)^2/(p^2 − q^2​)}
