수학동아 - 폴리매스
함께 풀고 싶은 문제
창의력을 기를 수 있는 수학 문제 또는 퍼즐을 내는 곳입니다.
[창의 퍼즐] 일주일 전에는 40위대였던 내가 이번주에는 30위?!

..제목은 농담입니다. 저 저 애니 제목도 제대로 몰라요.
정말 유명한 퍼즐인데, 여러분도 풀어보면 좋을 거 같네요.
1, 2, 3, 4, 5, 6, 7, 8, 9, 0을 적절히 조합해 다음 열자리 수를 만들어라:
abcdefghij에 대하여
a는 1의 배수이다.
ab는 2의 배수이다.
abc는 3의 배수이다.
abcd는 4의 배수이다.
abcde는 5의 배수이다.
abcdef는 6의 배수이다.
abcdefg는 7의 배수이다.
abcdefgh는 8의 배수이다.
abcdefghi는 9의 배수이다.
abcdefghij는 10의 배수이다.
원본은 알렉스 벨로스의 저서 '이 문제 풀수 있겠어?'라는 퍼즐 도서에서 가져왔습니다.
당연히 책을 읽으셨다면 유리하기에(뒤에 답지가 있으므로)스스로 양심에 맞춰서, 풀이 첨조해주시기 바랍니다.
