Answer with Explanation:
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.
