together is
A. 12600
B 7200
C. 86400
D 14400
​

Answer 1

Answer:

Step-by-step explanation:

let the event of 5 girls sitting together be 1 event.

so,the permutation of 5 boys and 1 group of girls will be:

=>6!

=>720

now the permutation of 5 girls will be:

=>5!

=>120

thus,their permutation of the both would be

=>720*120

=>86400 (answer)
