Rony can type in 1 hour = 32/6 = 16/3 pages
Jony can type in 1 hour = 40/5 = 8 pages
Working together, they can type in 1 hour = 16/3 + 8 = 40/3 pages
Now, 40/3 pages can type in = 1 hour
1 page can type in = 3/40 hours
110 pages can type in = (3*110)/40 hours
= 33/4 hours
= 8.25 hours
= 8 hours (.25*60)min
= 8 hours 15 min (Ans)
