100 books are distributed to Class A and Class B. The number of books in Class A is 20 times less than that in Class B. How many books are there in Class A and Class B respectively?
Solution: Class A is assigned to X copies, and Class B is assigned to 100-x copies.
X=5( 100-x)-20。
x=500-5x-20
6x=480
x=80
∴ 100-x=20
A: Class A is assigned 80 books and Class B is assigned 20 books.
