Five people A, B, C, D and E are seated about a round table. Every chair is spaced equidistant from adjacent chairs.
(i) C is seated next to A.
(ii) A is seated two seats from D.
(iii) B is not seated next to A.
Which of the following must be true?
- 1.D is seated next to B.
- 2.E is seated next to A.
Select the correct answer from the codes given below:
- A.1 only
- B.2 only
- C.Both 1 and 2
- D.Neither 1 nor 2
▶ Answer & Explanation
Correct answer: C. Both 1 and 2
Given that C is next to A and A is two seats from D, there are two possible arrangements relative to A. If C is to A's left, D is two seats to A's right. If C is to A's right, D is two seats to A's left. B is not next to A, meaning B must occupy the seat between D and C in one case, and between C and D in the other. In both valid arrangements, D is seated next to B, and E is seated next to A. Therefore, both statements must be true.
