수학동아 - 폴리매스
함께 풀고 싶은 문제
창의력을 기를 수 있는 수학 문제 또는 퍼즐을 내는 곳입니다.
대표이미지는 다양한 지식과 정보가 넘쳐나서
한번 들어가면 빠져나올 수 없는 폴리매스 카페
https://cafe.naver.com/polymathfun
의 로고입니다!
한 4층 건물에서 불이 놨다.
4층에만 사람 몇명과 개가 있었다.
빨리 탈출해야 하는데 계단 등 탈출할 곳은 모두 막혀서
탈출할 수 있는 방법은 오직 화재 대피 장치 뿐이다.
이 장치는 도르래에 줄과 바구니 2개를 달아서
한쪽에 올라타면 내려갈 수 있게 만든 장치이다.
경비원은 90, 아내는 210, 개는 60, 아이는 30의 무게라고 하자.
각 바구니는 넷을 모두 태울 수 있다.
그러나 추나 물건들은 올려놓을 수 없다.
그리고 바구니 둘의 무게는 30보다 더 차이날 때가 없어야 한다.
모두 탈출하는 방법을 쓰시오.
단, 개나 아기는 경비원이나 아내의 도움 없이 바구니에 오를 수 없다.
