How many arrangements can be formed if 6 BOYS and 4 GIRLS were to take seats with the middle seat belonging to a girl and the rest of boys???

This question was asked to me by a friend to help her daughter but unfortunately I was not able to justify how the answer was 120. Its a question with the answer already given and the person just needs to justify how the answer came to be.

Please help.

The "6boys and 4girls" part is really there in the question.

When i was trying to answer the question, I made my own assumption that the "middle seat" meant that a girl must be in the middle of the 6 boys.

I see. Well I don’t see how we can solve an incomplete question. There’s definitely something wrong in it.
