<PRE><B>Question 955510</B>
25 men take 20 days working 8hours a day to complete a job.how many days will 15 men take to compete the job.working 10 hours a day

Let x= amount of time it takes 15 men to complete the job working 10 hours/day
25 men takes 8*20=160 hours to complete the job
1 man take 160*25=4000 hours to complete the job
Thus, the job takes 4000 man-hours to complete
15 men working 10 hr/day completes 150 man-hours of work per day
Sooo
150x=4000
x=26 2/3 days----these are 10-hour days

CK
(26 2/3)(10)(15)=4000
4000=4000
Hope this helps---ptaylor
