Answer:
.............................
Step-by-step explanation:
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.
