Correction: if mean is 60 then 1, 2,4,x ,256,find the value of x.

Solution:

Mean = Mean is average values of given Number.

Formula of Mean = Sum of observations ÷ Number of observations

Mean = 1 + 2 + 4 + x + 256 ÷ 5

Mean = 7 + x + 256 ÷ 5

Mean = 263 + x / 5

60 = 263 +x/5

60 × 5 = 263 + x

300 = 263 + x

300 - 263 = x

x = 37

Therefore, Required Value of x is 37.
