You can put this solution on YOUR website! a piece of work can be done by 40 men in 48 days. after 15 days, 18 men were transferred to another job. how many more days will the remaining men finish the job?
-----------------------
40*48 = 1920 man-days are required for the job.
---
For 15 days, 40*15 = 600 man-days were done.
-----
That leaves 1920-600 = 1320 man-days to be done.
----
If 18 men leave, 22 men remain on the job.
----
# of days required will be 1320/22 = 60
========================================
Cheers,
