Answer 2

The total number of books between Ancient and Medieval history is 10.

• The total books are 64 and are arranged in a specific order.
• The book from the left at the 25th position is of ancient history. Similarly, medieval history is 30th from the right.
• So, there are 34 more books after medieval history, from the right.
• The medieval history book is, thus, at the 35th position from the left.
• The number of books between ancient and medieval history is 35-25=10.
