║⊕ANSWER⊕║

Let the number of novels and other books be 2x and 7x

GIVEN

Total no: of novels = 1600

                           2x = 1600

                             x = 800

Other books = 7x

                     = 7 * 800

                     = 5600

Total no: of books (including the novels) = 5600 + 800

                                                                  = 6400
