Answer 1

$\textbf{Here is your answer}$

$\textbf{Given}$

AM of 10 observation = 10

GM of 10 observation = 15

$\textbf{Now We know}$

${(GM)}^{2}$ = AM×HM

=> ${(15)}^{2}$ = 10×HM

=> 225 = 10×HM

=> HM = $\frac{225}{10}$

=> HM = $\frac{45}{2}$

=> HM = 22.5

Answer 2

Step-by-step explanation:

Given:-

AM of 10 observation➟10

GM of 10 observation➟15

We know that

$\boxed{\sf GM^2=AM\times HM}$

➟$\sf 15^2=10\times HM$

➟225=10×HM

➟HM=225/10

➟HM=22.5
