Question 794277
Try rechecking the question carefully for placement of the number values.  Repost the question as it should be.  The question here asks how many MORE men to take MORE time to do the work.  The rates of the participating men would be additive, so adding MORE men should require LESS TIME to do the work.  


Do you see how this works?  
If 5 men do the job in 6 hours, 
Then MORE than 5 men should do the job in LESS THAN 6 hours.
More men, get the job done in less time.


From our end seeing what you asked so far, we do not know which numbers appear in the wrong places.  Best is for you to recheck and then repost.
