9 typist can type 31 page in 1 hour.How many typist are required to type 217 pages in 1 hour.​

Answer 1

Answer:

63 typists

Step-by-step explanation:

In 1 hour, 31 pages can be typed by 9 typists.

If no. of page decreases, the no. of typists also decreases. So, we will use direct proportionality, here.

In 1 hour, 1 page can be typed by 9/31 typist.

In 1 hour, 217 pages can be typed by 9/31 × 217 typists = 63 typists.
