Question

Five friends A, B, C, D, and E are sitting in a row. B is to the immediate right of D. C is to the immediate left of E. D is not at either end. Who is sitting at the extreme left?

• A. A
• B. B
• C. D
• D. C

Hint:

For seating arrangement problems, list all conditions and assign positions systematically. Use a diagram or slots (e.g., \_ \_ \_ \_ \_) to visualize the row. Start with constraints that limit positions (e.g., “not at ends”) and build pairs (e.g., DB, CE) to fit the arrangement. Test each possible configuration and verify all conditions are met.

Answer 1

The Correct Option is A

To determine the person at the extreme left, we must arrange the five friends based on the provided constraints.

1. Core Principles:

- Adjacent Placement: Refers to immediate right or left positioning.
- End Positions: The leftmost and rightmost seats.
- Logical Sequencing: Utilize clues to establish the correct order.

2. Constraints:

- B occupies the seat immediately to D's right.
- C occupies the seat immediately to E's left.
- D is not positioned at either end of the row.

3. Sequencing Process:

- D's exclusion from end seats means D can be in positions 2, 3, or 4.
- B's adjacency to D on the right dictates their paired placement.
- C and E form a pair, with C preceding E.
- The row comprises 5 seats, numbered 1 (leftmost) to 5 (rightmost).

4. Possible Configuration:

• If D is in seat 2, B is in seat 3.
  The C-E pair can then occupy seats 4 and 5.
  This leaves A for seat 1.

Arrangement: A (1), D (2), B (3), C (4), E (5)

5. Verification of Constraints:

• B (3) is immediately right of D (2) → Condition met.
  C (4) is immediately left of E (5) → Condition met.
  D (2) is not at an end → Condition met.

Conclusion:

The individual seated at the extreme left is A.
