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.
这题的意思是不是从7,14,21..........98这14个数字中选出7个,问其余7个的和。 但(1) 是什么意思? 答案是B,但有很多选择啊,所以sum也该不一样啊! |
