If 5 men can paint 100 meters long in 10 days of a 8 hours each. in how many days of 6 hours each will 8 men paint a wall 30 meters long?
---------------------
10 8 hr days = 80 hours
5*80 = 400 man-hours for 100 meters
400 m-h/100 meters = 4 m-h/meter
-----
30*4 = 120 m-h to do 30 meters
120 m-h/8 men = 15 hours
15 hr/6 hr/day = 2.5 days
