Question

The relation among AM, GM and HM is

• A. $AM\times GM=HM$
• B. $HM=\sqrt{AM\times GM}$
• C. $G{M}^2=AM\times HM$
• D. $A{M}^2=GM\times HM$

Answer 1

Answer: (C)

$G{M}^2=AM\times HM$

For any given numbers, their means, Arithmetic mean (AM), Geometric mean, (GM) and Harmonic mean are related by the relation
$G{M}^2=AM\times HM$
