Show the answer and the worked solution
Correct answer: D. E
Worked solution
- C = seat 1; B = seat 2 (next to C); A = seat 3 (middle); D = seat 5 (extreme right).
- The only remaining seat, 4, must hold E.
- The row is C, B, A, E, D, so second from the right is E.
Answer: E.
The idea
Place every fixed position first; if exactly one seat and one person remain, the arrangement is forced and no case-checking is needed.
Shortcut. C, B, A and D fill seats 1, 2, 3 and 5; the one unnamed seat, 4 — second from the right — must be E's.
Common trap. "B" — the person second from the left; the question asks for second from the right.
