Re: [計量] 印度網站的Q 數題
我想您第二題好像有點錯耶
12=(x-3)*n+5, x & n must be positive
then, 7=(x-3)*n, and (x-3) could be 1 or 7
thereby, x=4 or 10
right?
※ 引述《ckyoung (小土)》之銘言：
: 補兩題
: : In a company, there are 54 members. If Wednesday has more number of birthdays
: : than on any other day of the week, then
: : Col A: The least number of birthdays on Wednesday
: : Col B: 8
: : Ans: A
: : i do have no idea.........
: 54/7 = 7 餘 5
: 因此要至少 9人 才會最多
: : Given that there are 'x' boxes and the balls are arranged in such a way that
: : no ball is left. If the number of boxes is reduced by 3 and if 12 balls are
: : arranged in them, then 5 balls are left behind, what is the original number
: : of boxes 'x'?
: : i didn't find the answer.......
: 12 / (x-3) = ? 餘 5
: 因此 x-3 = 7
: x = 10
