Question

P, q and r are three typists who working simultaneously can type 216 pages in 4 hours . In one your, r can many pages more than q as q can type more than p . During a period of five hours, r can type as many pages as p can seven hours. How many pages does each of them type per hour ?

Answer 1

Answer:

Step-by-step explanation:

Let the number of pages typed in one hour by P, Q and R be x,y and z respectively. Then

x+y+z = 216/4 = 54 ————— 1

z-y = y-x = > 2y = x+z ———–— 2

5z = 7x = > x = 5x/7 ————— 3

Solving 1,2 and 3 we get x = 15,y = 18, and z = 21
