FIVE boys CAN be placed in 5! ways

set the positions for boys first -b-b-b-b-b-

now see the dash . at the dashes girls can be placed fulfilling the requirement of the question.

so there are 3 girls and 6 places for girls to occupy.

it can be done in 6*5*4 ways= 120.

so total no of ways= 5! * 120 = 120*120 = 14400 ways
