KHALID   R print in 1h= 32/6. E print in 1h= 40/5. both (R+E) print in 1h = 32/6+40/5page.since 40/3page in 1h so 110page in 3/40*110h.

Number of pages typed by ronald in 1 hour = 32/6
= 16/3.
Number of pages typed by elan in 1 hour = 40/5
= 8.
Number of pages typed by both in 1 hour = (16/3+8)
=40/3.
Time taken by both to type 110 pages = (110×3/40)hrs
= 8×1/4hrs
= 8 hrs 15 min.

krishna   Ronald takes 6 hours to type 32 pages,number of pages Ronald can type in one hour is 32/6 = 16/3

Elan takes 5 hours to type 40 pages,number of pages Elan can type in one hour is 40/5 = 8.

Number of pages typed by both in 1 hour = (16/3+8) = 40/3.

How much time will they take,working together to type 110 pages?

Use cross multiplication method to solve this:

1 hour 40/3 pages

? 110 pages

? = (110)*(3/40) = 8.25 hours = 8 hours 15 minutes
