If 6 men can do the job in 14 days, it will take 1 man 6 times as long
so. 1 man will take days

You can read this as: what part of the job can be done by 1 man in 21 days
if 1 man can do 1 job in 84 days

So, 1 man can do 1/4 of the job in 21 days
And 4 men can do 4 times as much, or 1 job, done in the same amount tof time
It takes 4 men to do the job in 21 days
