8 men working together, can complete a job in 5 days. In how many days can 5 men (working together) complete the same job?
Ah, I see. What if we had ten men instead of eight?
Sure, let me calculate that for you. If ten men working together can complete the job in five days, then the total work done is 10 men x 5 days = 50 man-days. Now, if five men have to complete the same job, then the number of days required will be 50 man-days / 5 men = 10 days. So, it will take 5 men 10 days to complete the job if ten men can do it in five days.
