수학동아 - 폴리매스
함께 풀고 싶은 문제
창의력을 기를 수 있는 수학 문제 또는 퍼즐을 내는 곳입니다.
원모양의 투명한 돌림판 2개가 있다.
이 돌림판은 6개의 합동인 부채꼴 칸으로 나누어져 있는데, 각각의 칸마다 빨강색, 노랑색, 파랑색 중 하나를 선택하여 색칠할 수 있다.
<색 조합>
빨강 + 빨강 = 빨강
노랑 + 노랑 = 노랑
파랑 + 파랑 = 파랑
빨강 + 노랑 = 주황
빨강 + 파랑 = 보라
노랑 + 파랑 = 초록
두 돌림판의 모든 칸에 색칠한 뒤, 두 돌림판을 겹친다고 할 때, 다음 물음에 답하여라.
단, 둘중 한개의 돌림판을 회전하는것도 가능하며, 두 돌림판의 부채꼴칸 위치가 반드시 일치할 필요는 없다.
(1) 각 돌림판에 빨강과 노랑색만 칠할 수 있다고 하자. 이때, 부채꼴칸에 상관없이 색으로 구별되는 칸 수는 최대 몇개일까?
(2) 각 돌림판에 빨강 1칸, 노랑 2칸, 파랑 3칸 을 색칠한다고 할때, 색으로 구별되는 칸 수는 최소 몇개일까?
