After the votes are tallied, Kent Mark  is told only the fraction of votes that he  recieved.  Suppose he recieved less than (1/n) of the  votes. Show that he cannot have won  the election.

We assume that sum of number of votes  in that the election be S  Suppose Kent Mark win the election  then all  other candidates ,each of them  gets number of votes be a fraction less   than (1/n)that means he received less  than (1/n)S votes.Hence,sum of number of votes  in that election less tan  n.(1/n)S=S  This  contradiction shows that  Kent Mark cannot have won in   that election(Q.E.D)
