An executive receives an annual salary of 600,000 and his secretary a salary

of 180,000. A certain task can be performed by the executive working alone in 4 hours.

If he delegates the task to his secretary it will require him 30 minutes to explain the work

and another 45 minutes to check the finished work. Due to the unfamiliarity of the

secretary to the task, it takes her an additional time of 6 hours after being instructed.

Considering salary costs only, determine the cost of performing the task by each method,

if the secretary works 2,400 hours a year and the executive 3,000 hours a year.

Solution:

If the executive works alone: 800.00

If the executive delegates the work to his secretary: 737.50
