"这是谁的房间？"

Translation: Whose room is this?

[verticordian]

whose is this room should also be correct

"Whose is this room" is not a proper English sentence. When you do a Google search for that exact phrase it only returns 32 results. Most of the sites listed are non-English sites.

When you search Google for "Whose room is this", it returns 29,500 results.

I have to disagree, your suggestion should not be accepted.

lol made the mistake in English and said "Who's" even though English is my first language

If I type in who's verses whose, it should count either way
