[창의 퍼즐] [물리?? 대수??] 삶은달걀 vs 구운달걀

삶은달걀 10 명(마리??)과 구운달걀 10명이 있다.
삶은달걀과 구운달걀들은 줄다리기 시합을 하기로 했다.
삶은달걀 3명과 구운달걀 5마리가 시합했을때는 줄이 어느쪽으로도 움직이지 않고 제자리에서 멈추었다.
삶은달걀 4명과 구운달걀 5마리가 마지막으로 시합해 시합은 삶은달걀의 승리로 끝났다.
각 삶은달걀은 힘의 크기가 서로 같고, 구운달걀끼리도 힘의 크기가 서로 같다.
구운달걀 1명의 힘이 30N(힘의 단위) 일때 삶은달걀 1마리의 힘은 얼마인가?
(풀이 꼭 적어주세요.)
