C.20 D.30 解:A.B.C.D 考虑二人同时从A .B两地出发相向而行.那么应该需要= 二人同时从A .B两地出发背向而行.那么应该需要= 二人同时从A .B两地出发同向而行.分别为=30 =20 (4)若干名战士排成8列长方形的队列.若增加120人或减少120人都能组成一个新的正方形队列.那么.原有战士人.

A.2 B.30 C.60 D.50 答案:D 这个三位数与它的反序数除以四的余数应该相等. 不妨设这个三位数是ABC.则它的反序数为CBA.于是有ABC-CBA=4的倍数.即100A+10B+C-=4的倍数.整理得99(A-C)=4的倍数.即可知A-C是4的倍数即可.但是不能使这两个三位数的差为0.所以分别有5,1,6,2,7.3,8,4,9,5四组.每组中分别有10个.那么共有50个. (6)有若干条长短.粗细相同的绳子.如果从一端点火.每根绳子都正好8分钟燃尽.现在用这些绳子计量时间.比如:在一根绳子的两端同时点火.绳子4分钟燃尽,在一根绳子的一端点火.燃尽的同时点第二根绳子的一端.两根绳子燃尽可计时16分钟. 规则:①计量一个时间最多只能使用3条绳子. ②只能在绳子的端部点火. ③可以同时在几个端部点火. ④点着的火中途不灭. ⑤不许剪断绳子.或将绳子折起. 根据上面的5条规则下列时间能够计量的有. A.6分钟 B.7分钟 C.9分钟 D.10分钟 E.11分钟. F.12分钟 答案:A.B.C.D.F.只有11分钟计量不出来. 查看更多

Are you tired of the puzzles you usually do? Sudoku is a new choice. Sudoku consists of the Japanese characters Su (meaning “number”) and Doku (meaning “single”), but it was not invented in Japan. It was created by Howard Garnes in 1979. The puzzle was first introduced into Japan by Nikoli Puzzle Company in 1984. In 1986, Kaji Maki, the president of Nikoli made the rules strict and clear. Soon in the same year Sudoku became popular in Japan. In November 2004, The Times, a British newspaper, first printed it in the newspaper. It became an international hit in 2005. Now Sudoku becomes very popular all over the world.
The rule of the puzzle is to fill in the grids (格子) so that every row, every line and every 3×3 box has the numbers 1 to 9. Here is a Sudoku. Please relax and enjoy. It’s fun!
