Directions for question :
In 2022, on the occasion of their 450th year of being established, the Order of the Jesuit Missionaries, who founded the chain of St Xavier’s Schools in India, decided to honour the Fathers as well as the Principles of their Indian schools who helped propagate quality education in India.
For that, they had to choose one of the schools where they would carry out this landmark ceremony at. In the final contention were St Xavier’s Collegiate School Kolkata, St Xavier’s School Durgapur, St Xavier’s School Mumbai and St Xavier’s School Ranchi. St Xavier’s Schools in India as per rule had one Principal per school, and all the schools in India were represented by their individual Principals in the selection.
The eventual winner was determined through several rounds of voting by all the Principles of all the St Xavier’s Schools. In any round of voting, the school receiving the minimum number of votes in that round got eliminated. The surviving St Xavier’s School after the last round of voting would get the chance to host the ceremony.
Each Principal was allowed to cast votes for at most two schools in all rounds of voting combined. Hence, a Principal would become ineligible to cast a vote in a given round if both the St Xavier’s Schools he voted for in earlier rounds were out of contention in that round of voting. A Principle was also ineligible to cast a vote in a round if the St Xavier’s School he represented was in contention in that round of voting. As long as the Principal was eligible, he had to vote for only one contesting St Xavier’s School in any round of voting.
The following incomplete table shows the information on St Xavier’s Schools that received the maximum and minimum votes in different rounds of voting, the number of votes cast in their favor, and the total votes that were cast in those rounds.
