Solution: If there are X books on science and technology, the number of books on literature and art is 3(x+33)/5.

Because science and technology books are one-third of the sum of literature books and comics.

So 3(x+33)/5+33=3x.

The solution is x=22. 3(x+33)/5=33

So there are 22 books on science and technology and 33 books on literature and art.
