- Number of hours worked a day: 8 hours
- Total number of workers: 20 workers
- Specific period of time: 3 months — 90 days (January — March), minus weekends and public holidays.
Assuming that weekend and public holidays = 24 days
We subtract 24 from the number of days within the 3 months
90–24 = 66 days
Hence;
Man-hour = 8 x 20 x 66
= 10,560 hours.
