※ 引述《Exciaa (Louvre)》之銘言：
: A certain city with a population of 132,000 is to be divided into 11
: voting districts, and no district is to have a population that is
: more than 10 percent greater than the population of any other district.
: What is the minimum possible population that the least populated
: district could have?
: 解答 x + 10*(1.1x)＝132,000
: 得出x＝11,000
: 請問各位高手這樣解的思路是什麼阿??
: 我一直想不透為什麼要假設10*1.1x
: 請解惑一下吧 感謝!!
最少人那區有 ==> x人
剩下10區都剛好比最小那區多10% ==> 1.1x人
最少人那區 ＋ 剩下10區人 = 全部的人
Ｘ ＋ 10*(1.1x) = 132,000
得X
