Consider the following statements related to measure of central tendency of $50$ positive numbers
1. Median is not influenced by extreme values in set of numbers
2. The harmonic mean is unreliable if one or more of the numbers is non-zero which of the above statement is/are correct

$M\left(x_1,x_2,x_3\dots \dots \dots \dots x_n\right)$ defines a measure of central tendency based on $n$ values $x_1, x_2, x_3, \dots \dots \dots x_n$
consider the following measured of central tendency
(1) Arithmetic mean
(2) Median
(3) Geometric mean which of the above measure satisfied/ satisfies the property

$\frac{M\left(x_1,x_2,x_3\dots \dots \dots x_n\right)}{M\left(y_1,y_2,y_3\dots \dots \dots y_n\right)}=M·\left(\frac{x_1}{y_1},\frac{x_2}{y_2},\frac{x_3}{y_3}, \dots \dots ,\frac{x_n}{y_n}\right)?$
