Question

Wanda’s will power is 25% in convincing people to vote for her. She needs 50% of the vote to win. Assuming everyone votes, in order for Wanda to win what percentage of people must already be planning on voting for her?

Answer 1

Answer:

34 % of the people must already planning to vote for Wanda

Explanation:

Let there are 100 people in the town

It is given that Wanda will convince 25 % of people vote for her

Now let there are x people who are planning to vote Wanda

Then 100-x people are not planning to vote Wanda

She have to convince 0.25 ( 100-x) people to get 50% of the vote and to win

So $0.25(100-x)+x=50$

$25+0.75x=50$

x = 34

So 34 % of the people must already planning to vote for Wanda
