Answer:
Assume that there are 100 unit voters.
10% doesn't cast their votes, so now remaining voters are 90units.
Again 10% votes are invalid so 90*10/100=9
Valid votes are 90-8=81 now
Given that winning candidate gets 54% so 81*54/100=43.74
Another candidate= 81-43.74=37.26
Given that the of winning is 1620 votes.
43.74-37.26=6.48units=1620
1unit=1620/6.48=250
100unit= 25,000
