Are you sure OA is E because I got answer as D.
Here is my explanation.
Let the minimum population be X
population of all other 10 cities will be 1.1x each so total will be 11X.
Now X+11X=132,000
12X=132,000
X=11,000
So the answer is D
I also tried with picking number but got the same answer 11,000.
Please check the OA again.

Hi guerrero,
rakeshd347's explanation is correct, so there must be a transcription error somewhere. The correct answer IS D.
