Each typist types 1 page in 5 minutes. If you had only one typist, they would type 20 pages in 5*20 = 100 minutes. Therefore you need 100/10 = 10 typists to type 20 pages in 10 minutes.

There is no guarantee that these other typists can type two pages in five minutes so I cannot answer this question based on the fact that the typing speed of all the typists has not been established.
