Question

Using the same seating arrangement, who is at the rightmost position?

• A. B
• B. D
• C. E
• D. C

Hint:

For rightmost position, check valid arrangements and ensure all constraints are satisfied.

Answer 1

The Correct Option is C

- Step 1: Valid arrangement: A, C, B, D, E or A, C, B, E, D.
- Step 2: Rightmost (position 5): A, C, B, D, E has E; A, C, B, E, D has D.
- Step 3: Constraint: D not at end, so A, C, B, E, D is invalid. Only A, C, B, D, E is valid.
- Step 4: Rightmost = E.
- Step 5: Check options: Option (3) is E, which matches.
- Step 6: Confirm D's constraint eliminates other arrangements.
