The question given below consists of two statements

Solution

From statement I alone, we get, Clues: 1. F scored more marks than W but scored less number of marks than B and C. 2. D, who is the second highest scorer, scored more number of marks than A and B. Inference: From clue 1, we get, C, B > F > E From clue 2, we get, _ > D > _ > _ > _ > _ The final arrangement is as follows: C > D > B/A > A/B > F > E Or C > D > B > F > A/E > E/A So, C is the highest scorer. From statement II alone, we get, Clues: 1. A scored more marks than W but scored less number of marks F and C. 2. B scored more number of marks than at least three students. Inference: From clue 1, we get, C, F > A > E From clue 2, we get B 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.
