What is the remainder when the positive integer x is divided by 6?
(1)When x is divi
ded by 2, the remainder is 1; and when x is divided by 3, the remainder is 0.
(2)When x is divided by 12, the remainder is 3.
--------------------------------------------------------------------------------------------------------------------------------------------------------
【答案】
D
这题我选的B
(1)怎么也能得出答案呢?那如果X=3的话,也满足(1)的条件哇,但是除6的话不就是不行了吗?
本人数学不是很好,望高人解答...........

X=3的时候除6余3 没有规定比6小的数就不能除6
这题只要把数字都列出来就一目了然
