Question

$H_{1}, H_{2} are \underline{\underline{H . M}'s} between a, b then \frac{H_{1} + H_{2}}{H_{1} H_{2}} =$

Moderate

A

$\frac{a . b}{a + b}$
B

$\frac{a + b}{a b}$
C

$\frac{a - b}{a b}$
D

$\frac{a b}{a - b}$

Solution

$\frac{1}{H_{1}} + \frac{1}{H_{2}} = \frac{1}{a} + \frac{1}{b} \Rightarrow \frac{H_{1} + H_{2}}{H_{1} H_{2}} = \frac{a + b}{a b}$
