You can put this solution on YOUR website! Let x=number of days it takes 60 men to finish the job when working hours are reduced by 25%
It takes a total of 40*30*8=9600 man-hours to finish the work
8-(1/4)*8=6 hrs which represents the reduced working hours
Sooooo:
60*x*6=9600
360x=9600
x=26 2/3 days
Hope this helps---ptaylor
