Enterprise and wages

The enterprise operates a total 162 workers, and their average salary is M dollars. If the company has hired an additional 18 employee whose average wage would be the S dollars, it will reduce the overall average salary by 3.6%.

Calculate the value of the proportion of their salaries M/S.

Correct answer:

x=M/S =  1.5625

Step-by-step explanation:

162+18162M+18S=(13.6/100)M 162+18162M/S+18=(13.6/100)M/S 162+18162x+18=(13.6/100)x x=M/S=1.5625 

(162 x+18)/(162+18) = (1-3.6/100)x

(162·x+18)/(162+18) = (1-3.6/100)·x

6.4x = 10


x = 10/6.4 = 1.5625

x = 25/16 = 1.5625
