Question

If M + Z= 75 and M - Z = 1.4 ,then find the mean , median and mode of the distribution

Answer 1

M + Z = 75 ...(1)

M - Z = 1.4 ...(2)

Subtract equation (2) from (1). Then

2Z = 73.6

Z = 36.8

Put the value of Z in Equation (1)

M + Z = 75

M + 36.8 = 75

M = 75 - 36.8 = 38.2

M = 38.2

Now By the Formula :

3M = Z + 2x

3(38.2) = 36.8 + 2x

114.6 = 36.8 + 2x

114.6 - 36.8 = 2x

77.8 = 2x

x = 38.9

Now

Mean = x = 38.9

Median = M = 38.2

Mode = Z = 36.8
