50 men working 10 hours a day is 500 man-hours
It takes 500 man-hours to make 1200 boxes
Each hour 1200/500 boxes can be made.
2.4 boxes can be made per man-hour.
.
To make 3200 boxes, how many man-hours are needed?
3200/2.4 = 1333.33333 man-hours.
With 40 men working, 1333.33333/40 = 33{{{1/3}}} hours total.
