Suppose that 5 workers can complete a certain task in 12 days.
Find the number of man-days to complete
5 * 12 = 60 man-days
;
If there are 15 workers, how many days would it take for them to finish the same task?
let d = number of days required if there are 15 men
15d = 60
d = 60/15
d = 4 days for 15 men to do the job
