You can put this solution on YOUR website!
+600+ men can last +28+ days on the given food
Twice as many men could only last half that time, so
+1200+ men can last +14+ days
--------------------------------
1/3 as many men can last 3 times as long, so
+400+ men can last +42+ days
-------------------------------
Twice as many men can last half that time, so
+800+ men can last +21+ days
You end up with +600+%2B+200+=+800+ men, so
21 days is the length of time they can last
