Answer 1

Given : in factory the coefficient of variations of wages of urban and rural workers are 52%and 66% respectively and their standard deviation are 26 , 40 respectively

60% of the workers are urban.

To Find :  overall average( in rs) of the workers​

Solution:

similar Question with slightly different data.

https://brainly.in/question/26703311

Mean of urban  = a

Mean of rural  =  b

Coefficient of Variation = (Standard deviation /Mean) * 100 %

urban

=> 52 = ( 26 / a) * 100

=> a = 50

rural  

66 = ( 40 / b) * 100

=> b = 2000/33

60% of the workers are urban

40 %  of the workers are rural

=> overall average( in rs) of the workers​  =  50 * 0.6  + (2000/33)*0.4

= 30 + 24.24

= 54.24  

overall average( in rs) of the workers​ = 54.24
