당신은 이상한 방안에 갇혔다
그리고 100명의 사람들이 있다.
잠시후 스피커에서 소리가 들려왔다
''지금부터 10명만 탈출을 시켜주겠다.사람을 죽이던 합의하던 너네들 마음대로 하라''
그러자 사람들이 술렁이면서 서로 말한다
''합의를 해도 먼저 나가면 이득아니야?''
''싸워도 지면 못나가니까 합의하느게 이득아닐까?''
그리고 사람들은 결정을 했다
싸우자는 사람은 60명, 1/6이 이탈했다
합의하자는 사람은 40명, 1/5이 이탈했다
그러면 싸우자는 사람은 몇명이고 합의하는 사람은 몇명일까?그리고 방에 남은 사람은 몇명일까?
싸우자는 사람은6명을 뽑았고 합의하자는 사람은 4명을 뽑았다
보너스!문제!
이거 맞추면 부분해결 줌
제일 친환경적인 칫솔은?
1번 대나무 칫솔
2번 재사용 칫솔
3번 플라스틱 칫솔
4번 일회용 칫솔
