As per the question, since "no district has a population that is more than 20 percent greater than the population of any other district", then the populations of 11 districts should be in the range of x and 1.2x
To minimize the value of x, we should make only one district to have the minimum number of population and the rest 10 districts to have 1.2x of population.
x + (10 ∗ 1.2x) = 130,000
13x = 130,000
x = 10,000
Answer is B.

Solution
As "no district has a population that is more than 20 percent greater than the population of any other district", then the populations of 11 districts should be in the range: x and 1.2x.
So we want to minimize x. To minimize x we should make only one district to have that # of population (minimum possible) and the rest 10 districts to have 1.2x # of population (maximum possible).
x+10∗1.2x = 130,000
13x = 130,000
x = 10,000
Answer: B.
