题目：

In the year following an eight-cent increase in the federal tax on a pack of cigarettes, sales of cigarettes fell ten percent.  In contrast, in the year prior to the tax increase, sales had fallen one percent.  The volume of cigarette sales is therefore strongly related to the after-tax price of a pack of cigarettes.

The passage is primarily concerned with
N=a+b+c=XYZ, abc连续，xyz连续，问N除以5的余数 （1）a除以5余1 （2）x除以5余1 思路：根据连续整数的性质， 任何三个连续的整数中一定有一个是3的倍数，且这三个连续整数之积是6的倍数。因此可知a+b+c=3b=XYZ, 则xyz肯定是3的倍数， 条件1， a除以5余1时，a的尾数可能为1或者6，这时b的尾数为2或者7，c的尾数是3或者8，则xyz的尾数为6或者1，则xyz除以5的余数为1，充分 条件2， x除以5余1，则x可能为1或者6，此时可以算出xyz为123或者678，此时xyz除以5的余数为3，充分 ---------------------------------------------------------- 我觉得以上解法没有利用到XYZ连续这个条件。老师是否可以讲解下，谢谢。
