Question

6 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, each working 6 hours a day?​

Answer 1

Answer:

20 days

Step-by-step explanation:

6 typist take 5 hours to type manuscript in 16 days.

If each had 1 hour, 6 typists would take 16 x 5 = 80 days

if 1 typist had 1 hour, he would take 80 x 6=480 days.

4 typists had 1 hour= 480 / 6 = 80

4 typists have 6 hours so 80 / 6 =20

Therefore 20 Days
