Does anyone know how to figure these things out? What the answers are?

In voting for 4 candidates, the outcomes are reported:

ADBC -8
DACB -5
BADC -3
BDCA -1
DCAB -2

1) What is the total number of votes?
2) Determine winner using a majority rule?
3) Determine winner using a pluarlity rule?
4) Determine winner using a Borda count?
5) Hare method? who wins?
6) When using the HAre method, which round did i declare a winner?
7) who wins when using the pairwise comparison method
8) Who is the winner by using a tournament method?

Hi Softtail Rider;

Looks like there were 19 votes cast.

4)

Borda count, if there are four candidates in an election then a candidate will receive 4 points each time they are ranked first, 3 for being ranked second, and so on, with a candidate receiving 1 point for being ranked last. Used to determine the MVP ion major league baseball

So D with 16 points wins by Simple Borda Count.

Here is what I found for the hare system, which they claim is actually used in Australia.
