Question

11. If A can type 10 pages in 5 minutes and B can
type 5 pages in 10 minutes then, working
together, how many pages can they type in 30
minutes?
Solution

Answer 1

Answer:

Step-by-step explanation:

A can type 10 pages - 5 min

B can type 5 pages - 10 mins

A can type one page = 5/10=1/2

B can type one page = 10/5=2

So both do → 2 +1/2=5/2

Thus 1 minute work done =5/2

30 minutes work done=5/2*30

=75 pages

Answer 2

Answer:75

Step-by-step explanation:

Therefore both together they can type 75 pages in 1 minute. Together, in 10 minutes, they can type 25 pages. Therefore, in 30 minutes they can type 75 pages. Or, A can type 60 pages and B can type 15 pages in 30 minutes.
