Question

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

Answer 1

mean = sum of all numbers / total number

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

27×5 = 103+x

x = 135-103 = 32

Answer 2

mean = 27

no of observation : 5

sum of observation : 24+25+26+28+X

mean = 24+25+26+28+X/5

27(5) = 103+X

135 - 103 = X

X = 32
