The right answer is Option C.
Step-by-step explanation:
Hardcover books = 15
This represent 12% of total books.
Let,
x be the total number of books, therefore,
12% of x = 15
Dividing both sides by 0.12
As, 15 of them are hardcover books, the remaining will not be hardcovers;
Remaining books = Total books - hardcover books
Remaining books = 125 - 15 = 110
115 books are not hardcover.
The right answer is Option C.
