Question

if the mean of 26, 28, 25 ,x,24 is 27 ,find the value of x

Answer 1

That's easy. Look mean of the five equals to
26+28+25+x+24÷5 = 27
So, 103+x÷5=27
That means 103+x= 27*5
103+x= 135
x=135-103
x=32
That's the answer.

Answer 2

Given,

The mean of 26, 28, 25, x, and 24 is 27

To Find,

The value of x.

Solution,

The formula for calculating the mean of some observations is

Mean = Sum of observations/Number of observations.

So,

(26+28+25+x+24)/5 = 27

(103+x)/5 = 27

103+x = 135

x = 32

Hence, the value of x is 32.
