Answer
Soup B is declared the winner using the pairwise comparison method.
Work Step by Step
With the pairwise comparison method, each candidate is compared with every other candidate. For each pair of candidates, if one candidate is ranked higher than the other candidate on a majority of ballots, then the higher-ranked candidate receives 1 point. If the two candidates tie, then they each receive 0.5 points. After all the comparisons have been made, the candidate who receives the most points is declared the winner.
We can compare Soup A and Soup C. We can find the number of ballots with Soup A ranked higher than Soup C, and the number of ballots with Soup C ranked higher than Soup A.
Soup A: 34
Soup C: 30 + 6 + 2 = 38
Since Soup C is ranked higher than Soup A on more ballots, Soup C receives 1 point.
We can compare Soup A and Soup B. We can find the number of ballots with Soup A ranked higher than Soup B, and the number of ballots with Soup B ranked higher than Soup A.
Soup A: 34
Soup B: 30 + 6 + 2 = 38
Since Soup B is ranked higher than Soup A on more ballots, Soup B receives 1 point.
We can compare Soup B and Soup C. We can find the number of ballots with Soup B ranked higher than Soup C, and the number of ballots with Soup C ranked higher than Soup B.
Soup B: 34 + 30 + 2 = 66
Soup C: 6
Since Soup B is ranked higher than Soup C on more ballots, Soup B receives 1 point.
We can compare Soup A and Soup D. We can find the number of ballots with Soup A ranked higher than Soup D, and the number of ballots with Soup D ranked higher than Soup A.
Soup A: 34
Soup D: 30 + 6 + 2 = 38
Since Soup D is ranked higher than Soup A on more ballots, Soup D receives 1 point.
We can compare Soup D and Soup C. We can find the number of ballots with Soup D ranked higher than Soup C, and the number of ballots with Soup C ranked higher than Soup D.
Soup D: 2
Soup C: 34 + 30 + 6 = 70
Since Soup C is ranked higher than Soup D on more ballots, Soup C receives 1 point.
