Chapter 11.1, Problem 72E
APPLICATIONS
Classroom Use A small school has 100 students who occupy three classrooms: A, B. and C. After the first period of the school day, half the students in room A move to room B, one- fifth of the students in room B move to room C, and one-third of the students in room C move to room A. Nevertheless, the total number of students in each room is the same for both periods. How many students occupy each room?
