Answer 2

To determine the minimum number of voters who could have voted for the winning giraffe, let's break down the information given:

- There are 315 voters divided into 9 districts. - Each district is divided into 7 sections. - Each section has 5 voters. - The winner in each section is determined by the majority of votes in that section. - The winner in each district is determined by the giraffe who won the majority of sections in that district. - The overall winner is the giraffe who won the majority of districts.

To find the minimum number of voters who could have voted for the winning giraffe, we need to consider the scenario where the winning giraffe wins by the smallest possible margin in each section, district, and overall.

Let's calculate the minimum number of voters for the winning giraffe:

1. In each section, the winning giraffe needs to win by a margin of 1 vote. Since each section has 5 voters, the minimum number of voters for the winning giraffe in each section is 3 (2 votes for the losing giraffe and 3 votes for the winning giraffe).

2. In each district, the winning giraffe needs to win the majority of sections. Since each district has 7 sections, the minimum number of voters for the winning giraffe in each district is 21 (3 voters for the losing giraffe and 21 voters for the winning giraffe).

3. Finally, the winning giraffe needs to win the majority of districts. Since there are 9 districts, the minimum number of voters for the winning giraffe overall is 189 (21 voters for the losing giraffe and 189 voters for the winning giraffe).

Therefore, the minimum number of voters who could have voted for the winning giraffe is 189.

Please note that this calculation assumes that there are no ties in any section or district, and the winning giraffe wins by the smallest possible margin in each case.
