10. Each employee on a task force is either a manager or a director. What percentage of
the employees on the task force are directors?



(1) Arithmetic mean salary of the managers on the task force is $5000 less than the
average salary of all employees on the task force.
(2) Arithmetic mean salary of the directors on the task force is $15000 more than
the average salary of all employees on the task force.
