Step-by-step explanation:
Given:-
The sum of three measure of centrat tendency is 40.
To find:-
Find value of 4 median - mean ?
Solution:-
Let mean be X
Let median be M
Let mode be Z
Given that
The sum of three measure of centrat tendency = 40
Mean + Median + Mode = 40
X+M+Z = 40------(1)
We know that
The relationship among mean,median and mode
=Mode = 3 Median - 2 Mean
=> Z = 3M -2X -------(2)
Put the value of Z in the equation (1) then
=>X+M+3M -2X = 40
=> (M+3M) +(X-2X) = 40
=> (4M)+(-X) = 40
=> 4M -X = 40
Therefore, 4Median -Mean = 40
Answer:-
The valis of 4Median -Mean for the given problem is 40
Used formulae:-
- Mode = 3 Median - 2 Mean
- Mean ,Median and Mode are called measures of central tendency.
