Question

Ten men working for 6 days can complete
5 copies of a book. If there are 8 men
working to complete 4 copies of the book,
how many days will it take?
​

Answer 1

Answer:

10 workers had to work 6 days to make 5 books. So 10x6 =60… So 60 days worth of work (for one guy) to make 5 books. 60/5=12 … Or 12 days per person per book. (Most inefficient workers!). So 4 books would take 48 days (4x12=48). But you can split that among 8 workers… so 48/8=6 so collectively they would take 6 days…
