Calculate the number of voters who voted first as fractions: VEтАЛ=32500├Ч0.94=30550 and VBтАЛ=13500├Ч0.8=10800. Then find target gender count and subtract.
Students often calculate the percentage of total population rather than percentage of those who actually voted.
Calculate voters who voted in Town E and B
Using the formula VvotedтАЛ=VtotalтАЛ├Ч(1тИТ100PтАЛ): For Town E, 32500├Ч0.94=30550. For Town B, 13500├Ч0.8=10800.
VEтАЛ=30550,VBтАЛ=10800
Calculate target counts for E (Male) and B (Female)
Town E: Female is 40%, so Male is 60%. Male voters = 30550├Ч0.6=18330. Town B: Female is 45%. Female voters = 10800├Ч0.45=4860.
MaleEтАЛ=18330,FemaleBтАЛ=4860
Find the difference
Subtract the number of female voters in Town B from the number of male voters in Town E.
18330тИТ4860=13470
B is correct because the calculated difference between male voters in town E and female voters in town B is 13470.
