Answer:
The combined amount of votes of candidate A and candidate B received are 12.
Explanation:
Given:
Ratio of the students who voted for candidate A compared to candidate B was 2 : 1.
If candidate A received = 8 votes.
Now, to find the the combined amount of votes candidate A and candidate B received.
Let the number of votes of candidate B be
.
According to question:
Ratio of the votes = Number of votes


By cross multiplication we get:

Dividing both sides by 2 we get:

Candidate B received = 4 votes.
Now, the combined votes of candidate A and B = 8 + 4 = 12.
Therefore, the combined amount of votes of candidate A and candidate B received are 12.
