- My earlier solution is wrong
alka has 6 vacant places to choose from whereas sonu will always have to sit opposite to alka

- first make a circular table and make be seated alka and sonu now you will see you have two space for 2 male singers and 2 spaces for 2 female singers
so it can be done = 2 x 2
= 4 ways - 12 years agoHelpfull: Yes(13) No(12)
- first make the seating arrangement for alka and sonu
intially alka has 6 vacantplaces to choose from
and sonu is left with 3
thereby other female and male members are left with 2
therefore 6*3*2*2=72 - 12 years agoHelpfull: Yes(2) No(12)
