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
