The population of a city vote for one among 4 political parties, A, B, C and D. 25% of the voters are committed to party B, 25% to party C and 10% to party D. 10% of the total voters fluctuate and can vote for any party. 50% of the voters are female and 50% of the voters committed to party D are male. Of the voters who fluctuate, half are female. Party B does not have any committed female voters while party C does not have any committed male voters. If all the voters except those who fluctuate cast their votes, what percent of the male votes will be won by party A?

A. 16.66%

B. 25%

C. 30%

D. 33.33%

E. 35%

Let the votes be 100, so % can be taken as numbers..

Now concentrate ONLY on male votes..

There are 50 male voters..

1) actually voted is 50-5=45..As it is given 10 are fluctuating of which HALF are females

2) 5 of these voted for D, so left 45-5=40As only 10 voted for D, of which HALF are male.

3) 25 of these voted for B, so left 40-25=15

4) none voted for C..So 15 voted out of 45 for A..

%=15/45=\(33\frac{1}{3}\)%

D
