A) a) 12,000 B) b) 10,800 C) c) 10,900 D) d) 11,000 E) e) 11,100
Let x = number of people in smallest district   x*1.1 = number of people in largest district   x will be minimised when the number of people in largest district is maximised   10*x*1.1 = 11x = total number of people in other districts   So we have 11x + x = 144k   x = 12,000   a) 12,000nswer : a) 12,000
