Answer: RITA

To determine this, look at who is higher ranked in each column of the preference schedule (and by how many voters).


# of




130 120 100 150
1st P T T S
2nd R R R R
3rd S S P P
4th T P S T

In the first column, we see that 130 voters prefer Paul to Rita. But Rita is preferred to Paul in each of the other columns, giving Rita 370 votes (120+100+150). So, Rita beats Paul in a head-to-head matchup. Since Rita won, we put her name in the appropriate cell of the head-to-head matchup table.

  Paul Rita Sarah Tim
Paul ---------- RITA    
Rita ---------- ----------    
Sarah ---------- ---------- ----------  
Tim ---------- ---------- ---------- ----------
