Data Arrangement Worksheet 13 - Intermediate Level (chronological order) | 20 Questions

Question 1

Nine persons are to be seated in a single row of 9 seats; one seat is vacant. The final arrangement is consistent with the given constraints. Answer the question: - A total of 8 persons are seated in 9 seats, with exactly one seat vacant. - The number of persons to the left of the vacant seat is one more than the number of persons to its right. - The person next to Nihal is a fixed person (clue to force uniqueness). Question: In a row of 9 seats with one seat vacant, what occupies the seat exactly between Nihal and Kaira?

Incomplete Information Strategy: Fixed Vacancy
The constraint on the vacant seat's relative position fixes it immediately.
Final arrangement (Seats 1-9): 1: Aarav; 2: Yash; 3: Nihal; 4: Empty; 5: Sahil; 6: Kaira; 7: Fatima; 8: Cyrus; 9: Gaurav
The calculation for the question is done on the fixed layout.
Verification:
- Seat configuration: 5 persons left, 3 persons right of Empty (P5).
- Final positions of X and Y verified.

Question 2

8 persons sit around a circular table facing the center. Who sits second to the left of Eshan?

Diagrammatic Approach (Circle)
Place the 8 persons on a circle. For 'facing the center', define directions:
- Left of a person is clockwise; right is counter-clockwise.
From Eshan's position, move two seats to the left per the facing rule.
Validate the mapping and confirm the second-left occupant.
One valid circular order (clockwise): Gaurav -> Wafa -> Fatima -> Rhea -> Uma -> Aarav -> Yash -> Eshan
Verification:
- Left/right mapping consistent with facing.
- Second-left computed via modular indexing.
- Computed person matches final arrangement index shift.

Question 3

Eight people Bhavya, Zoya, Gaurav, Eshan, Yash, Vihaan, Laksh, Wafa sit in a row facing north. Clues: - Yash sits at an even-numbered position (2, 4, 6, or 8). - There are exactly two persons between Yash and Wafa. - Laksh does not sit at any extreme end. - Gaurav sits at position 8. Question: At which position from the left does Wafa sit?

Logical Flow:
1. Yash is at position 6 (even position).
2. Distance between Yash and Wafa is exactly 3 seats → Wafa at position 3.
3. Laksh cannot be at position 1 or 8 → Laksh at position 2.
4. Gaurav is fixed at position 8.
Arrangement: Position 1: Vihaan; Position 2: Laksh; Position 3: Wafa; Position 4: Bhavya; Position 5: Eshan; Position 6: Yash; Position 7: Zoya; Position 8: Gaurav

Question 10

Six people sit in a row facing North. Conditions: - Wafa sits at the extreme right end (Position 6). - There are three people sitting between Ira and Zoya. - Mira sits third to the right of Zoya. - Neither Laksh nor Nihal sits at any extreme end. Question: Who is sitting second from the left end (Position 2)?

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: Zoya, Laksh, Nihal, Mira, Ira, Wafa
- Case 2: Zoya, Nihal, Laksh, Mira, Ira, Wafa
Since the person at Position 2 is either A or C (and both cases are valid), the answer is 'Cannot be determined'.
