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.
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.

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.
