Seating Arrangement Deduction

This problem requires arranging five individuals (A, B, C, D, E) in a line using logical clues.

Analyzing Seating Clues

  • People: A, B, C, D, E
  • Arrangement: Linear row
  • Clue 1: B is the last person. Row looks like: _ _ _ _ B
  • Clue 2: E is not at the ends (position 1 or 5).
  • Clue 3: E is somewhere to the left of B. Combined with Clue 2, E must be in position 2, 3, or 4.
  • Clue 4: E is not adjacent to D.
  • Clue 5: C is positioned between D and A, meaning the sequence is either D C A or A C D.

Determining the Final Arrangement

Starting with _ _ _ _ B based on Clue 1.

Consider the A C D block from Clue 5. Placing it would yield A C D E B. This violates Clue 4, as E is next to D.

Now consider the D C A block from Clue 5. The arrangement D C A E B satisfies all conditions:

  • D C A forms the block (Clue 5 satisfied).
  • E is in the 4th position, not an end (Clue 2 satisfied).
  • E (4th) is not next to D (1st) (Clue 4 satisfied).
  • E (4th) is to the left of B (5th) (Clue 3 satisfied).
  • B is last (Clue 1 satisfied).

The confirmed seating order is D C A E B.

Answering the Question

The question asks: Who is to the right of D?

Observing the arrangement D C A E B, the person directly to the right of D is C.
