Question

During a class election the ratio of students who voted for candidate A compared tocandidate B was 7: 4. If candidate A received 21 votes, what is the combined amount ofvotes candidate A and candidate B received?

Answer 1

Given: Ratio of students that voted for A compared to B is 7:4

A recieved 21 votes so let B recieve x votes.

So as the given ratios,

`(7)/(4)=(21)/(x)`
`x=(21*4)/(7)=12`

Hence, combined votes received by candidate A and B is 12+21=33
