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.
