Answer 1

Answer:

3 pages.

Step-by-step explanation:

No. of pages typed by A+B+C in hour = 900/20*8 = 45/8.

Let  C type 4x pages.

Therefore, all type x pages per hour.

According to the question,

C - B = B - A

2B = A + C = x + 4x = 5x

=> B = 5x/2.

x + 5x/2 + 4x = 45/8

=> 15x/2 = 45/8

x = 3/4.

No of pages C can type in 1 hour = 4 *3/4 = 3.
