  Solution: - Given

                     Average Salary of m Male + f Female = $2000.

                    let 'b' be the average salary of female employees 

                   Average salary of male = $(b+200)

                   To Find average salary of Female=?

         Average salary of male(m) + Average salary of female(f)= $2000

⦁

                   (b + 200)+ b = 2000     …….      Average salary of male is given

                         b+b =2000-200 

                          2b = 1800  

                          b=1800/2   

                           b = 900      

           Answer = Average Monthly salary of female is $900
