Answer:
Required number of total ways = 288
Step-by-step explanation:
Number of novels = 3
Number of ways to arrange 3 novels = 3!
Number of dictionaries = 4
Number of ways to arrange 4 dictionaries = 4!
Now, There are two types of articles in the shelf to be arranged so to arrange them , Number of ways = 2!
We need to find the number of ways in which all 7 books can be arranged on the shelf so that the books of the same kind must be kept together.
So, Required number of total ways = 4! × 3! × 2!
= 24 × 6 × 2
= 288
