The number of ways in which 9 boys and 5 girls can be arranged in two buses each having numbered seats, three in the front and five at the back such that at least four girls should always be together is ?

This was a question in an entrance exam that i found interesting and thought i should share.

TopNewestKinda awarkd. 14 people, (3+5)x2 = 16 seats. This is kinda weird for me. And what's the front and the back? Is it interact with the number of girls? (Like 3 girls in the front and 1 in the back is OK or not?)
