A certain city with apopulation 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?
10,700
10,800
10,900
11,000
11,100
还没有题目讲解（毕出老师会陆续发布对官方考题的解读，请保持关注）。
试着想这么一个情景，10个区将人口少的机会都分给其中一个，10家超过12000，只有1家低于12000（12000=132000/11）
那么，最小人口区（A）应该满足：其他区人数相等，并且是A的1.1倍。
X+10Y=132000
1.1X=Y
X=11000
=====1.1倍是可以的
