Correct Answer: Option C
Number of pages typed by Ravi in 1 hour = 32/6 = 16/3
Number of pages typed by Kumar in 1 hour = 40/5 = 8.
Number of pages typed by both in 1 hour = (16/3 + 8) = 40/3.
Therefore, Time taken by both to type 110 pages = (110 x 3/40) hours.
= 8(1/4) hours (or) 8 hours 15 minutes.
