Let there are X number of male employees and X number of female employees.

Then total salary of all female employees

= X * 15000 = 15000 X

Also, total salary of all male employees

= X * 15000 = 15000 X

Then total salary = salary of all male employees +salary of all female employees

=. 15000 X + 15000 X = 30,000 X

Total number of employees

=. Male employees + female employees

=. X + X =2X

Then average salary of all employees =
total salary total number of employees

=.30000X 2X

=.15000

Thus, average salary is 15000
