Around a circular table, the number of distinct seating arrangements of four people, counting rotations as the same, is
Correct answer: B. six
- A. four
- B. six
- C. twelve
- D. twenty four
Explanation
Circular arrangements of n people number n minus 1 factorial, because fixing one person removes the equivalent rotations, so for four people it is 3 factorial, which is 6. In a row the same four people could be arranged in 24 ways. The difference is exactly the factor of four rotations.

About Seating Arrangements
Seating arrangement problems place people or objects in a line, circle, row or multiple rows according to positional clues. They require handling adjacency, left and right, facing directions, opposite seats, fixed positions and relative order, with circular arrangements differing because rotation does not create a new arrangement.
