Answer 1

Answer:

30 days

Step-by-step explanation:

In first case:

Number of typists= 4

Number of hours 1 typist work in a day= 6

Working hours of 4 typists in a day= 4*6= 24(1 day)

Total Working hours of 4 typists in 20 days= 24*20= 480hours

In second case:

Total time taken to type a book= 480hours

Number of typists= 2

Number of hours 1 typist work in a day= 8

Working hours of 2 typists in a day=2*8= 16

Number of days 2 typists will take to do the same job=$\frac{480}{16}$ = 30 DAYS

Hope this helps you...
