책 다섯 권이 있다. 1책은 200쪽, 2책은 400쪽이고 나머지 두 책은 600쪽이다. 그리고 모든 책들은 하나에 10000원이다. 그러나 가끔씩 찢어진게 있을 수 있는데 50쪽당 하나씩 나온다. 그리고 책으로 안 사고 하나하나를 쪽으로 사면(?) 한 쪽당 30원이다.                                                      

문제 1. 모든 책들을 쪽으로 사면 얼마인지 각각 구하여라.                         

문제 2. 1번 책 2권, 2,3,4,5번 책 한 권을 산다면 찢어진 게 몇 개가 나오는가? 

(풀이 필수)
