Choice B - wrong - 132000-10800 = 121200. Thus average of other 10 districts would be 12,120 which is more than 10% of 10800
Choice A - wrong (it's lesser than choice B)
Choice C - wrong - 132000-10900 = 121100. Thus average of other districts would be 12110 which is more than 10% of 10900
Choice D - Right - 132000-11000 = 121000. Thus average of other districts is 12100 which is exactly 110% of 11,000. Hence correct
