[Grammar] May I know how old are you/you are?

[Checkmate]

"May I know how old are you/you are?"

When I was at school, my teacher said the correct one was "May I know how old are you" but I don't think so. Was my teacher right?

No, your teacher was wrong.

It must be either "May I know how old you are?" or "How old are you?"

I'm sorry. I clicked "Go back" and accidentally posted the same thread once again.

No problem. I didn't notice the close time of the two postings.
