***
5 men working 4 days=20 man-days to unload 5000 tons of lumber
to unload 10,000 tons of lumber will require 2*20=40 man-days
How long will it take 8 such men to unload 10,000 tons of lumber? 40/8= 5 days

You can put this solution on YOUR website! 5 men take 4 days to unload 5,000 tons of lumber.
------------------------------------------------
1 man will take 5 times as long to unload the 5,000 tons, so
1 man takes 20 days to unload 5,000 tons of lumber.
---------------------------------------------
1 man will take twice as long to unload 10000 tons, so
1 man takes 40 days to unload 10,000 tons of lumber.
----------------------------------------------
8 men will take 1/8 of that time to unload 10000 tons, so
8 men take 5 days to unload 10,000 tons of lumber.
