premise: each region receives share in proportion to total population share...
Premise: % revenue received were decreased for Korva, but population increased...
conclusion?
A)doesn't matter.
B) it can be possible that population grew by larger %
C) let M and G each had x people and each's population increased by y% each.
and K initially had p and increased by q%. where y>q
now initial share = p/(p+2x)
new share = 100p+pq/ (100p+pq +200x+2xy)
new share - initial share = 100p+pq/ (100p+pq +200x+2xy) - P/(p+2x)
100pp + 2pqx - 100pp -ppq - 200xp -2pxy / denominator = 2px(q-y) - ppq - 200xp /D
q-y<0 and thus numerator <0 and thus new share < initial share
Thus c) is the answer. it will explain why its share decreased...
D) let k initial=10, final=11,
m,g: 10000 and final 10002
thus initial: 10/20010= 4.9975 and final: 11/20015=5.49
thus even if numerical increase was smallest, share increased. thus not valid
E)say m's population doubled and k's increased by 90% and g's only 1%... still k can get more share..
IMO C
