Question

In an election, there are a total of 80000 voters and there are two candidates, X and Y. 80 % of the voters go for polls out of which 60 % vote for X. How any votes does Y get?

Answer 1

Well, from 80000 only 80% went to the polls, how many is that?

if we take 80000 to be the 100%, then how much is the 80%?

$\bf \begin{array}{ccll} amount&\%\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 80000&100\\ x&80 \end{array}\implies \cfrac{80000}{x}=\cfrac{100}{80}\implies \cfrac{80000\cdot 80}{100}\implies 64000=x$

now, from those 64000 60% voted for X, that means that the remaining 40% voted for Y, how many is that 40%?

well, if we take 64000 to be 100%, how much is 40%?

$\bf \begin{array}{ccll} amount&\%\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 64000&100\\ y&40 \end{array}\implies \cfrac{64000}{y}=\cfrac{100}{40}\implies \cfrac{64000\cdot 40}{100}=y$
