Six typists working 5 hours a day can type the manuscript of a book in 16 days. how many days will 4 typists take to do the same job, working 6 hours a day?

Please put explanation/solution


Sagot :

Let's find how many man-hours a book manuscript requires to finish typing

Time to finish one manuscript = 6 typists x 5 hours a day x 16 days = 480 typist-hrs

If there are 4 typists working 6 hours a day:

= 480 typist-hrs / (4 typists)(6hrs /day)

= 20 days
