The question given below consists of two statements

Solution

From statement I alone, we get, Q scored more marks than P but scored less number of marks than M and N. O, who scored second highest marks scored more number of marks than L and M. We get, N, M > Q > P We get, _ > O > _ > _ > _ > _ The final arrangement is as follows: N > O > M/L > L/M > Q > P Or N > O > M > Q > L/P > P/L So, N is the highest scorer. From statement II alone, we get, L scored more marks than P but scored less number of marks Q and N. M scored more number of marks than at least three students. We get, N, Q > L > P We get M is either highest or second highest or third highest mark scorer. Therefore, Data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question.
