### Mathland Election

A political commentator summed up an election result. Given that there were just four candidates and that the figures quoted were exact find the number of votes polled for each candidate.

### One or Both

Problem one was solved by 70% of the pupils. Problem 2 was solved by 60% of them. Every pupil solved at least one of the problems. Nine pupils solved both problems. How many pupils took the exam?

### Put Out the Flags

Tim and Beth both have a string of flags. Use the percentages to find out who has the most flags.

$20%$ of $30%$ of $40%$ of $£50$ can be written as $0.2 \times 0.3 \times 0.4 \times 50 = 0.06 \times 20 = 1.2$, so the answer is $£1.20$
Alternatively, $40%$ of $£50$ is $£20$. $30%$ of $£20$ is $£6$. $20%$ of $£6$ is $£1.20$.
