请教MATH12—Q32

看不明白啊，B可以吗？非常感谢~~

Q32:

Seven different numbers are selected from the integers 1 to 100, and each number is divided by 7.  What is the sum of the remainders?

(1)   The range of the seven remainders is 6.

(2) The seven numbers selected are consecutive integers.

A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.

B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.

C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

D. EACH statement ALONE is sufficient.

E. Statements (1) and (2) TOGETHER are NOT sufficient.

7的余数为 0 1 2 3 4 5 6 8 9

知道range=6 只可能是 0123456； A满足

如果是连续的整数， 则会有几种可能的余数， 得不到余数的和

选A吧

偶然来论坛一晃 看见道数学题。。

大概是这样吧 如果是连续7个整数 只要是连续的 不论是哪7个连续的整数

 除以7 余数肯定是0 1 2 3 4 5 6（顺序可能前后有变）  余数相加 结果会一直等于21. 所以B一个条件即可。

我们老师说B 对 我们都是只要是给出第二个条件就可以了
