Answer:
excluded number= 35
Step-by-step explanation:
mean of five numbers=27
so, sum of 5 numbers=27 x 5=135
let excluding number is x
now ,
sum of 4 numbers =135-x
mean=sum of 4 numbers/4=(135-x)/4
=> 27-2=(135-x)/4
=> 25 x 4=135-x
=> 100-135=-x
=> x=35
hence excluded number is 35

Answer:
Mean = sum of all observations
---------
no. of observations
27 = x
-----
5
x = 135
mean = 135 = 27
--------
5
If one no. is excluded, then -:
27-2 = 25 = x
-----
4
x = 25×4 = 100
mean = 100 = 25
--------
4
Sum of numbers in first case = 135
Sum of numbers in second case = 100
Excluded number = 135-100 = 35
