P, Q and R are three typists who working simultaneously can type 216 pages in 4hours. In one hour, R can type as many pages more than Q as Q can type more than P. During a period of 5 hours, R can type as many pages as P can during 7 hours. How many pages does each of them type per hour?
Is there any easy method to solve this??
