Answer:
30240 number of ways are there to seat them
Step-by-step explanation:
Total number of ways of arranging 9 people on 9 chairs in circular manners = (9-1)! = 8! =
number of ways A sit always sit next to B = AB together makes a single and
therefore total number of arrangements for this = 7+(AB) = 8 that is 8 persons sitting in circular manner
number of ways = (8-1)! =7! = 5040
likewise number of arrangements for A and C will be = 5040
Total number of ways such that A cannot sit next to B or C = total ways of 9 persons - total number of A always sitting next to B - total number of ways always sitting next to C = 8! - 7!-7!
= 40320- 5040-5040
= 30240
=
