Each of the following questions consists of a question followed three statements labeled I, II and III. You have to decide whether the data given in the statement(s) is/are sufficient for answering the question. Read all the statements carefully and seek all the possible combinations which could be sufficient for answering the question. A single combination of statements with least number of statements which could be sufficient for answering the question would be your answer.
I. B is lighter than A & D & heavier than E. II. A is heavier than B and lighter than D. III. C is heavier than B.
Who among A, B, C, D and E is the lightest?
A I and II only B I and II only C I, II and III
D II and III only E None of these
I. B is lighter than A & D & heavier than E.
II. A is heavier than B and lighter than D.
III. C is heavier than B.
On combining all the informations we know that E is the lightest among all the five persons. But on the other hand from statements I and III also, we get the same answer. Since, we require least combinations of statements to get the answer, hence (b) is the correct choice.
