Question : Height of teh stack of books = ?

Statement 1: Exactly 100 books are needed to completely cover the floor of the storage room
i.e. The height of the stack of books will be 100 times the height of room because all other 99 stacks will be mounted on h=just one stack
but the height of the room is unknown hence
NOT SUFFICIENT

Statement 2: The height of the room is 10 feet
but the height of the room is known but how many books are on the floor of the room is unknown hence
NOT SUFFICIENT

COmbining the two statements
Now we can deduce the the height of stack of books = 100*10 = 1000 feet

Answer: Option C
