This is a first few portion of the workings..The no. of book of both types in the end are 450 each..All you have to do is to work backwards and you will find the number of each books at first.

Wait.I don't think you can carry on either.We still don't know how much of each book were sold from 2/5 of the books.So it's not possible to find the number of books at first..The qn may be lacking in info.By the way,there should be two and not three book types.
