How many students attend Hogwarts school of witchcraft and wizardry each year?

I just read The Sorcerer's Stone again, and I want to know if others think it's the same as I do.
The answer is actually 280 if there are no expulsions. Thanks for playing.
Just to clarify...5 girls, 5 boys from each year...7 years...4 houses...

10x7x4=280

i dunno... ask harry

I forgot how many did...but isn't it around 50 first years every year or something? Huh, oh well...I should read that again.

There is no way to tell how many there are. The best thing to do is ask Harry.
