Answer:
First,
we need to select 7 among 15 for sitting around the first round table.
It can be done in (15C7) = 6435 ways.
Now,
the 7 persons can sit around the first round table in {(7 - 1)!} = (6!) = 720 ways for each of the above selection.
Similarly,
the remaining 8 persons can sit around the second round table in
{(8 – 1)!} = (7!) = 5040 ways for each sitting arrangement around the first round table.
So,
the answer is (6435*720*5040).
