Each student in a class of 40 students voted for exactly one of the three candidates A, B or C for the post of class representative. Did candidate A receive the maximum votes from the 40 votes cast?
A. Candidate A received 11 of the votes
B. Candidate C received 14 of the votes

Total number of student in class = 40

A) : Candidate A received 11 of the votes

Since, A received less than half the number of votes, then A did not receive the maximum number of votes.

Thus, statement A alone is sufficient.

B) : Candidate C received 14 of the votes

Now, A could have received more than 20 votes or even less than 14, since it cannot be determined, hence this statement alone is not sufficient.

=> Ans - (A)
