Approach:

- 1 Typist: 4 mins/page => 60 mins/15 pages OR 15 Pages/hour
- Total Pages to be typed: 1080
- Time available: 1 hour

- Total Number of typists required : 1080/15 => 72 Answer

Option B

Unless, I missed a trick in the question, I think this should be marked as a sub-600 level question.

Method to solve:

1 Page - 4 min
So, time for 1080 page = 1080x4 mins

1 hour = 60 min

total typist required = total time for 1080 pages / total time in 1 hour

=> total typist required = (1080 x 4) / 60

Ans = 72
