Question 1

Six people sit in a row facing North. Conditions: - Uma sits at the extreme right end (Position 6). - There are three people sitting between Cyrus and Yash. - Bhavya sits third to the right of Yash. - Neither Vihaan nor Diya sits at any extreme end. Question: Who is sitting at the immediate right of Bhavya?
Ambiguity Strategy: Proving Non-Unique Solution
Step 1: Fix D (P6). Use the 'three between' clue (Clue 2) to determine the positions of F (P5) and B (P1).
Step 2: Use E's position (Clue 3) to fix E (P4).
The arrangement is fixed at: B, P2, P3, E, F, D.
Step 3: The remaining people are A and C for positions P2 and P3. Clue 4 prevents them from being at the ends, leaving two cases:
- Case 1: Yash, Vihaan, Diya, Bhavya, Cyrus, Uma
- Case 2: Yash, Diya, Vihaan, Bhavya, Cyrus, Uma
The person immediately right of E is F in both valid cases, so the answer is uniquely determined.
