Understanding the Seating Arrangement Puzzle
This problem requires us to arrange seven individuals – A, B, L, M, S, T, and Z – around a circular table. Everyone is facing the center. We need to use the provided clues to determine their exact positions and then calculate the number of people between B and S, counting from S's left.
Step-by-Step Clue Analysis
Let's systematically decode each piece of information:
- Clue 1: M sits to the immediate right of T. This establishes a fixed pair in the clockwise direction: T followed immediately by M. We can write this sequence as T M.
- Clue 2: Only three people sit between M and A when counted from the left of M. Imagine you are M. The person immediately to your left is the first person in this count. Counting three people starting from M's immediate left neighbour, the next person you encounter is A. In a circle of 7 people, this implies A is seated three positions away clockwise from M, or opposite M. Let's place T at position 1 and M at position 2 (moving clockwise). M's immediate left neighbour is T (at position 1). Counting anti-clockwise from M: T (position 1) is the 1st person counted, the person at position 7 is the 2nd, and the person at position 6 is the 3rd. Therefore, A must be at position 5. Our arrangement looks like this: T(1) M(2) _(3) _(4) A(5) _(6) _(7).
- Clue 3: Only three people sit between T and Z. T is currently placed at position 1. Let's check the possibilities for Z:
- If we count clockwise from T (position 1): The people are M (position 2), the person at position 3, and the person at position 4. This would place Z at position 5. However, position 5 is already occupied by A. So, this direction isn't correct.
- If we count anti-clockwise from T (position 1): The people are at positions 7, 6, and 5. The next person in this direction would be at position 4. This means Z is at position 4. This placement is valid as position 4 is currently empty.
- Clue 4: L sits to the immediate right of S. This means S is immediately followed by L in the clockwise direction (S L). We have three empty seats: 3, 6, and 7. The pair 'S L' must occupy adjacent seats. Looking at the available seats, the only possibility for the S L pair is S at position 6 and L at position 7. The arrangement now is: T(1) M(2) _(3) Z(4) A(5) S(6) L(7).
Final Seating Arrangement
The only remaining person is B, and the only empty seat is position 3. Therefore, the final seating arrangement in clockwise order is:
| Position (Clockwise) | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
|---|---|---|---|---|---|---|---|
| Person | T | M | B | Z | A | S | L |
Answering the Question
The question asks: How many people sit between B and S when counted from the left of S?
- Identify the positions: B is at position 3, and S is at position 6.
- Determine the counting direction: Since everyone faces the centre, the "left of S" means moving in the anti-clockwise direction from S.
- Count the people between S and B anti-clockwise:
- Starting from S (position 6), the person immediately to the left (anti-clockwise) is A (at position 5). This is the 1st person.
- The next person anti-clockwise is Z (at position 4). This is the 2nd person.
- The next person anti-clockwise is B (at position 3).
- The people seated between S and B, when counting from S's left, are A and Z.
- Therefore, there are 2 people sitting between B and S when counted from the left of S.
Important Questions from Seating arrangement
