Question
In a conference hall, 13 chairs are arranged around a round table. Find the possible ways that 13 people can occupy the seats
Solution
The problem you're describing is a permutation problem. In permutations, the order of arrangement matters.
However, in this case, since the table is round, we have a circular permutation. The number of ways to arrange n items in a circle is (n-1)!.
So, for 13 people around a round table, the number of arrangements would be (13-1)! = 12!.
Therefore, the 13 people can be seated in 12! = 479,001,600 ways.

Select the correct answerStudy the following information and answer the given questions Sixteen chairs are seated around two concentric circular tables, containing equal number of chairs in each. There is equal distance between consecutive chairs on each table. Some people are facing inward while others are facing outward. Two seats in each table are vacant. 4 chairs (2 on outer table and 2 on inner table) each are along the same line. Note: 2 people facing same direction means either both are facing inside or both are facing outside. 2 people facing opposite direction means if one is facing inward, the other is facing outwards and vice versa Three chairs are arranged between K and H. Adjacent seats of H are vacant. P and A sit on different tables and face opposite directions. On the outer table where P is sitting, P is the one closest to A. E, who faces the centre, sits third to the right of A. S sits to the immediate left of P. Only two persons seated at the outer table are facing outward. K who sits on the outer table is closest to L who sits on inner table. L sits in a seat which is third from G's seat when counted in anti-clockwise direction. L faces the opposite direction of A K faces the centre. G sits adjacent to A. M sits in a seat second to the left of L's seat. Q sits in a seat second to the right of the person's seat who faces an empty seat of the inner table. W and M are facing each other and are on different tables and closest to each other. I is an immediate neighbor of M. G and Q face the same direction, sitting in different tables. The immediate neighbors of M face the opposite directions. L and H face same direction. In which seat is M seated with respect to G’s seat?
