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?

(A) 10,700

(B) 10,800

(C) 10,900

(D) 11,000

(E) 11,100

------------------------------------------------------------------------------------------------------------------------------------

【答案】D

【思路】假設the minimum possible population that the least population district could have=x

且假設其他10個voting district的人口 more than10percent

x+(x+0.1x)x10=132,000

x=11,000

求其他解法，感谢！
