DS:D是abc三个连续整数的乘积。问D是否可以被24整除?
1. abc三个数当中有两个odd
2. 这三个数字当中有一个是4
歌霏:选C,很明显就是3.4.5三个数
是否应该选B?
234, 345,456 的乘积都能被24整除。
自己搞错了-。-

a) is not sufficient
b) we could have b1 3*4*5, b2 2*3*4, b3 4*5*6, b1(60) cannot be divided by 24 b2&b3 could be divided by 24
Both A and B (c) we could have the anwser that is No
