Number of economic history books = 3
Number of English books = 4
Since all books different from each other, we can take total books = 3+4 = 7
So we have to arrange 7 unique books.
Total number of ways to do it = 7! = 5040
So the books can be arranged in 5040 ways.
Number of English books = 4
Since all books different from each other, we can take total books = 3+4 = 7
So we have to arrange 7 unique books.
Total number of ways to do it = 7! = 5040
So the books can be arranged in 5040 ways.
