Question

In how many ways can four persons A,B,C and D be seated at a circular table​

Answer 1

Given: Four people A, B, C and D.

To find: In how many ways can four persons A,B,C and D be seated at a circular table​ ?

Solution:

• Now we have not given how many seats are there, so assuming that round table is having 4 seats.

• Now we know that number of ways can n persons be seated at a circular table​  is:

                (n - 1)!

• So the number of ways will be :

                (4 - 1)! = 3! = 3 x 2 x 1 = 6

Answer:

          So in 6 ways can four persons A,B,C and D be seated at a circular table​ .
