수학동아 - 폴리매스
함께 풀고 싶은 문제
창의력을 기를 수 있는 수학 문제 또는 퍼즐을 내는 곳입니다.
[창의 퍼즐] 지나가던 사람님이 너무 빨리 따라와요ㅠㅠ
나는 삼*지를 10번, 반지의**을 3번, 실마릴*온을 1번을 읽었다. 그런데 삼*지는 한 권당 400쪽이고 10권이며, 반지의 제왕은 한 권당 430쪽이고 6권이며, 실마릴리온은 한 권당 530쪽이고 두 원이다.
문제 1. 책은 모두 몇 권이며 하루에 한 권의 책을 읽는다고 할 때, 책들을 모두 다 읽는 경우의 수는? (여기서 한 권은 (예: 400쪽)짜리 이다.)
문제 2. 책 한 권당 11000원이고 반지의 제왕과 실마릴리온은 13000원이라고 할 때, 책 세트 중 가장 많은 쪽 수와 가장 적은 쪽수의 책을 구하여라
(풀이 핈 )
