One definite point of the question is that both Rs. 337.50 and Rs. 213.75 are the multiple of the cost of a book.
Let us find the maximum number of books he sold. HCF of 33750 and 21375 is 1125.
So, with the price of Rs. 11.25/book he might had brought 30 books (30 x 11.25), and sold 19 books (19 x 11.25). So, he has 30 - 19 =11 books left.
