if 12 men working 2 hours a day take 10 days to complete a job, how long will 8 men working 6 hours a day take to do the same work?
Read Solution (Total 2)
-
- 5 days take to do same work.
12 men working 2 hours in a day means,
= 12 * 2hrs
= 24hours of work complete in 1day.
Therefore for 10 days,
= 10 *24hours
= 240hours of work done by 12men.
8 men working for 6hours in a day means,
= 8 *6hours
= 48hours of work is completed in 1 day.
Therefore,
= 240/48
= 5days take to work by 8 men for 6hours in a day. - 12 years agoHelpfull: Yes(3) No(0)
