6. There were five candidates in the school election. After $90 \%$ of the votes had been counted, the preliminary results were as
\begin{tabular}{ccccc} 
Henry & India & Jenny & Ken & Lena \\
14 & 11 & 10 & 8 & 2
\end{tabular}
shown on the right. How many students still had a chance of winning the election?
A 1
B 2
C 3
D 4
E 5
Solution
C

The 45 votes already cast are $90 \%$ of those available. So the remaining $10 \%$ is $45 \div 9=5$ votes. If Henry wins at least two of the five votes then he is certain to win the election. If India or Jenny win all five of these votes, they would be ahead of Henry. But if Ken or Lena secure five more votes, they would still be behind Henry. Hence only Henry, India and Jenny still have a chance of winning.
