问题 解答题

一个获奖号码是由五个不同的数字组成,数位与数字相同即可中奖,对1个为五等奖,对2个为四等奖,对3个为三等奖,对4个为二等奖,全对为一等奖.甲、乙、丙三人所猜的号码分别是:93715、15239和79538;结果三人获奖等级相同,且每个人猜对的数字的数位都不相邻.如果把三人获奖号码放在一起重新组号,则可获得一等奖.这个获奖号码是多少?

答案

由于每个人猜对的数字的数位都不相邻,

把三人获奖号码放在一起重新组号,则可获得一等奖.

所以每个人猜对的数不可能是5个,4个,3个,各人猜对的也不是一个数;

由此可知,他们都猜对了两个数,即获得了四等奖.

所以有1个数字必是两人共同所猜的数字,这个数字只能是3;

由于15239与79538的十位数都是3,

所以,乙丙两人同时猜中了3,则这与3相邻的数是猜错的,

则中奖号码的个数一定是5,百位一定是7;

由于获奖号码是由五个不同的数字组成,个位是5,

则乙猜中的一定万位1,丙猜中的一定是千位9;

综上可知,这个数是19735.

答:这个获奖号码是19735.

For Sparky, school was all but impossible. He failed every subject in the eighth grade. He flunked physics in high school, getting a grade of zero. Sparky also flunked Latin, algebra and English. He didn't do much better in sports. Although he did manage to make the school's golf team, he promptly lost the only important match of the season. There was a consolation(安慰) match; he lost that, too.

Throughout his youth Sparky was awkward socially. He was not actually disliked by the other students; no one cared that much. He was astonished if a classmate ever said hello to him outside of school hours. There's no way to tell how he might have done at dating. Sparky never once asked a girl to go out in high school. He was too afraid of being turned down.

Sparky was a loser. He, his classmates...everyone knew it. So he rolled with it. Sparky had made up his mind early in life that if things were meant to work out, they would. Otherwise he would content himself with what appeared to be his inevitable mediocrity(平凡).

However, one thing was important to Sparky - drawing. He was proud of his artwork. Of course, no one else appreciated it. In his senior year of high school, he submitted some cartoons to the editors of the Yearbook. Although the cartoons were turned down., Sparky was so convinced of his ability that he decided to become an artist.

After completing high school, he wrote a letter to Walt Disney Studios. He was told to send some samples of his artwork, and the subject for a cartoon was suggested. Sparky spent a great deal of time o it. Finally, the reply came from Disney Studios. He had been rejected once again. Anther loss for the loser.

So Sparky decided to write his own autobiography(自传) in cartoons. He described his childhood - a little boy loser and chronic underachiever. The cartoon character would soon become famous worldwide. For Sparky, the boy who had such a lack of success in school and whose work was rejected again and again, was Charles Schultz. He created the Peanuts comic strip(连环漫画) and the little cartoon character whose kite would never fly and who never succeeded in kicking a football--Charlie Brown.
