Club X has more than 10 but fewer than 40 members. Sometimes the members sit at tables with 3 members at one table and 4 members at each of the other tables, and sometimes they sit at tables with 3 members at one table and 5 members at each of the other tables. If they sit at tables with 6 members at each table except one and fewer than 6 members at that one table, how many members will be at the table that has fewer than 6 members?

预约讲师一对一题目解析课程这个数是23
这个数除以4余3，除以5余3，所以必定为4X5+3=23，所以有3个6人桌，一个5人桌

TOBEAWESOME回复331637w
这是同余定理的应用。一个口诀：和同加和，余同加余，差同减差。余同加余的意思是，如果一个数X除以a余c，除以b也余c（即余数相同），那么X可以写成X=d*n+c的形式，其中d是a和b的最小公倍数。
