一道数学prep题,求解答
A certain city with a population of 132000, is divided into 11 voting districts, and no district is to have a population that is more than 10% greater than the population of any other district. What is the minimum possible population that the least populated district could have?
A) 10700
B) 10800
C) 10900
D) 11000
E) 11100
我是这样算的:132000/11=12000
如果最小是11000的话,和平均人数12000相比减少了1000,所以最大应该是12000+1000=13000。
所以(13000-11000)/13000=0.15>10%,而题目说没有一个地方比另一个地方大10%的,矛盾了
我这样算哪里错了?求解答 |
