Question

A publisher employs 5 typists to type a book in 9 days. If the book needs to be typed out in 3 days,
how many more typists does the publisher need to hire?

Answer 1

Answer:

Equivalent hours worked by 6 typists in a day=6×5=30 hours.

Total hours needed to type a manuscript= (no. of days×hours worked in a day)=16×30=480 hours.

Now, equivalent hours worked by 4 typists working 6 hours= 4×6=24 hours.

Hours required to type a manuscript = 480 = no. of days× hours per day.

480=days× 24

No. of days= 20 days.
