Question
A, B, C and D are sitting around a circular table facing
the centre. Who sits to the immediate right of A? Statements: (I) C sits to the immediate left of A; only one person sits between C and D. (II) Only one person sits between A and B; C sits to the immediate right of B. A question is given, followed by two statements numbered (I) and (II). You have to decide whether the data provided in the statements is sufficient to answer the question. Read both the statements and select the appropriate answer.Solution
