Ronald and Elan are working on an assignment. Ronald takes 6 hours to type 32 pages on a computer and Elan takes 5 hours to type 40 pages. How much time will they take, working together on two different computers to type an assignment of 110 pages?
8 hrs 15 mins
Number of pages typed by Ronald in 1 hour = 326=163
Number of pages typed by Elan in 1 hour = 405=8
Number of pages typed by both in 1 hour = 163 + 8 = 403
Time taken by both to type 110 pages = 110×340=334hrs=8hrs15 min
