Question

Ifx and y are two numbers then their H. M.(Harmonic Mean) is given by H=​

Answer 1

Ifx and y are two numbers then their H. M.(Harmonic Mean) is given by H=2xy/(x+y)

Answer 2

If x and y are two numbers then their H. M.(Harmonic Mean) is given by

H = $\frac{2}{(1/x) + (1/y)}$

• Harmonic Mean is the mean that is calculated as the total number of observations present in the series divided by the reciprocal of every number in the series.

• The reciprocal of the average of the reciprocals is also defined as the Harmonic mean.

• Harmonic Mean is mostly used to find the relationships between fractions.
