If 8 people work for 60 days, how many days will it take for 6 people to complete the same work?
- 90 days
- 80 days
- 70 days
- None of these
Explanation
To solve this problem, we can use the concept of man-days:
8 people × 60 days = 480 man-days
Since the amount of work remains the same, we can set up an equation for 6 people:
6 people × x days = 480 man-days
To find the number of days, divide 480 by 6:
x = 480 ÷ 6
x = 80 days
