Question 65

A company CEO invited nine persons for a business meeting, where the host will be seated at a circular table. How many different arrangements are possible if two invitees X and Y be seated on either side of the host CEO?

Solution

Number of persons in the meeting = 9 + 1(host) = 10 persons

Except X, Y and the host the number of ways the other 7 persons are arranged = 7!

Now, X and Y can be seated on either side of the host i.e in 2 ways.

Total number of ways = 7! x 2 = 10080

Hence, option A is the correct answer.
