Question

If 4 typists work 6 hour a day, they can type a book in 20 days. How many days

will 2 typists take to do the same job, if each works for 8 hours a day?​

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.
