Answer 2

Let the cost of 1 book be x.

Step-by-step explanation:

To find the cost of 1 book, you need to divide,

the cost of 13 books by 13, or you can say,

assuming the cost of 1 book is x,

then, 13 x = 299.

So, the cost of 1 book is,

299/13 = 23

Hence, Rs. 23.

To find the cost of 3 books, just multiple the cost of 1 book with the 3,

23 x 3 = 69.

Hence, the cost of 3 books is Rs. 69.
