you really dont have to use a lot of algebra.
given (40/100)(V) = 942568 where V is the total number of votes
=> (60V/100) is the remaining and we were asked to find what % of remaining votes does he need to win
( he needs 10% more votes to win)
=> \((p/100)(60V/100) = 10V/100\)
=> p = 17%
Answer is D.
if you look carefully we dont even have to use the 942568 any where in our calculation. Hope it helps.
I got this problem correct using brute force algebra, but the process took to long. What is the most efficient method to solve problems like this one?
Mr. Kramer, the losing candidate in a two-candidate election, received 942,568 votes, which was exactly 40 percent of all votes cast. Approximately what percent of the remaining votes would he need to have received in order to have won at least 50 percent of all the votes cast?
