Answer:
16 days
Step-by-step explanation:
24 men working at 8 hours per day can do a piece of work in 15 days. In how many days can 20 men working at 9 hours per days do the same work.
------------------------
The job takes 24 men x 8 hrs/day x 15 days = 2880 man-hours
------------
2880 man-hours/(20 men x 9 hours/day) = 16 days
-----------------------
Another method:
15 days * 24/20 * 8/9 = 16 days
