Question

If M = 22, Z = 16 find mean.​

Answer 1

Answer:

Option ( b ) is correct.

Explanation :

By Empharical Formula ,

If Mode = z , Median = M,

Mean = x

Then ,

z = 3M - 2x

=> x = ( 3M - z )/2

Here ,

M = 22 , z = 16,

x = ( 3M - z )/2

=> x = ( 3 × 22 - 16 )/2

=> x = ( 66 - 16 )/2

=> x = 50/2

=> x = 25
