@Anindya_Sikdar Circular arrangements right?
@Anindya_Sikdar i didn't consider arrangement on circular table.... Did we have to consider it
Yes. I think we have to consider
The 30 people can be distributed in the 5 tables in 30C6×24C6×18C6×12C6×6C6=30!/(6!)^5
Now for each such distributions total no of circular arrangements=5!^5
Multiplying them we get 30!/6^5=(6×5)!/6^5
You got 11 after considering it? @Anindya_Sikdar
Yes all correct except Wednesday one
