How AM, GM and HM of the values of a variable are changed when the values are divided by a constant .

AM || GM || HM

AM || GM || HM

How arithmetic mean is changed when the values of the variable are added or subtracted by a constant number ?

If a value of a variable is zero, then what will be the value of A.M., G.M. and H.M. ?

If the values of a variable are in G.P, then prove that A.M., G.M., H.M. of the values are also in G.P.

If the values of a variable are multiplied or divided by constant, then how their median and mode are changed?

If a constant is added or substracted from the values of a variable, then how their median and mode are changed?

If HM and GM of two numbers are 10/9 and 3, then its AM is :
