in how many 15 people be seated around two round tables with seating capacities of 7 and 8 people
Read Solution (Total 5)
-
- initially 7 members are selected from 15 people =15c7 ways
then this 7 people can be arranged in 6! ways and
second table with 7!ways
total possible ways =15c7*6!*7! - 12 years agoHelpfull: Yes(41) No(6)
- for a circular table no. ways of seating = n-1!
so for first table = 7-1! = 6!
and for second table = 8-1! = 7!
so tatal ways = 6! x 7! ans - 12 years agoHelpfull: Yes(9) No(14)
- (15C7*6!*7!)+(15C8*7!+6!)
- 12 years agoHelpfull: Yes(3) No(3)
- 15c7*6!*7! no need of selecting people for other table
- 12 years agoHelpfull: Yes(1) No(2)
- initially 8 members are selected from 15 people =15c8 ways
then this 8 people can be arranged in 7! ways and
second table with 6!ways
total possible ways =15c8*7!*6!
