推 cmchen40:range是全距 不代表 餘數不重複 09/19 17:28
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.
Ans: B
我想問為什麼第一個不行??
RANGE是6的話
那麼不就等於0~6都有了嗎??
謝謝解答
