수학동아 - 폴리매스
함께 풀고 싶은 문제
창의력을 기를 수 있는 수학 문제 또는 퍼즐을 내는 곳입니다.
두명의 배 농부가 있다. 한사람의 이름은 배불러 이고 다른 한사람의 이름은 배고파 이다.
배고파가 거둔 배는 항상 먹음직스러웠고 배불러가 거둔 배는 맛있어보이지는 않았다.
두명의 농부는 수확한 배 30개씩 따서 바구니에 담고 시장에 팔러갔다.
배불러는 2개에 1000원, 배고파는 3개에 2000원을 받으려고 한다.
배불러는 다 팔면 15000원, 배고파는 다 팔면 20000원을 벌게 된다.
배고파는 같이 섞어서 5개에 3000원에 팔자고 제안한다.
두 사람은 모두 팔았다.
그런데 돈을 세어보니 번돈은 모두 35000원이 아니라 36000원 이었다.
1000원은 어디서 생긴걸까?
