Question

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

Answer 1

Step-by-step explanation:

10 workers complete the work in 12*4=48 hr

So, 1 worker would take 48*10=480 hr to do the work

Hence, he does 1/480 work in 1hr

so 8 workers at 6 hr a day will take 8 * 1/480 * 6= 10 days to complete the work
