Problem: In how many ways can 5 boys and 4 girls can be seated in a row so that they are in alternate position.
Solution:
First, we need to select a position for the first boy. There are 5 choices for the first boy.
Next, we need to select a position for the first girl. There are 4 choices for the first girl.
Now, we need to alternate the remaining boys and girls in the available positions. There are 4 remaining boys and 3 remaining girls, so there are 4! ways to arrange the remaining boys and 3! ways to arrange the remaining girls.
Therefore, the total number of ways to arrange 5 boys and 4 girls in alternate positions is:
5 x 4 x 4! x 3! = 2880
Hence, the correct option is (B) 2880.
