The number of ways the representative can be seated are:

720

(n-1)!

Since in a circular seating there is no condition of the end point and hence the arrangement may start from anywhere.

Here we are given 7 nations who are to be seated at a round table.

Hence, the number of ways of doing so is:

`(7-1)!=6!\\\\=6* 5* 4* 3* 2* 1\\\\=720`

Hence, the number of ways to do so is:

720
