The correct option is A 240
The printer prints 40 pages in 60 minutes and 80 pages in 120 minutes.
60 minutes = 1 hour
120 minutes = 2 hours
Therefore, the printer prints 40 pages in 1 hour and 80 pages in 2 hours.
This is an increasing pattern.
Difference between the terms (pages) = 80 - 40 = 40
The pattern is: 40, 80, 120, 160, 200, 240
Hence, the number of pages can be printed in 6 hours = 240
