Question

10 computer operators can type 120 pages in 2 hours. How many operators should work if the job is to be completed in 30 minutes?​

Answer 1

Answer:

40 operators should work

Step-by-step explanation:

120 pages in 2 hrs

In 1 hr = 120 / 2

In 1 hr = 60 pages

In 30 min = 60 / 2

In 30 min 10 operators can type 30 pages

Hence ,

1 operator can type only 3 pages in 30 min

So , 120 / 3

= 40
