수학동아 - 폴리매스
함께 풀고 싶은 문제
창의력을 기를 수 있는 수학 문제 또는 퍼즐을 내는 곳입니다.
함풀문 문제는 좋음, 단순문제로 평가된다.
1300개의 문제 중 4개가 삭제되었다.
삭제되지 않은 나머지 문제를 나열했을 때 6의 배수번째 문제의 평가 상태가 바뀌었다. (좋음이였으면 단순문제, 단순문제였으면 좋음)
그리고 단순문제를 맨 앞으로 나열한다.
또 다시 6의 배수번째 문제의 평가 상태가 바뀌고, 단순문제를 맨 앞으로 나열한다.
이 과정을 4번 반복했을 때, 단순문제의 개수를 구하여라.
(풀이필수)

최초의 단순문제, 좋음의 비율과 위치를 알아야 풀 수 있지 않을까요?

맞다 처음에는 단순문제가 없다라는 걸 쓰려고 했는데 까먹었네요
