Each employee is required to have two consecutive days off. How many regular employees are required? Round your answer to the nearest whole number.

Answer 1

Since the maximum requirement on any given day is 6, the reuirement must be more than 6.

Employee Numbers. /day	Mon	Tue	Wed	Thu	Fri	Sat	Sun

6				2	2	4	4
7	6	1	1	3	3	5	5

.

Since the weekly off of 6th and 7th employee can not be accommodated as per the reuirement of consecutive 2 days off, 7 employees would not be sufficient.

8 employees
