Enterprise and wages

The enterprise operates a total 162 workers and their average salary is M dollars. If the company has hire an additional 18 employees whose average wage would be the S dollars, would reduce the overall average salary in the company of 3.6%.

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

Correct result:

x=M/S =  1.5625

Solution:

162M+18S162+18=(13.6/100)M 162M/S+18162+18=(13.6/100)M/S 162x+18162+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 = 25/16 = 1.5625
