Answer 2

Answer:

The cost of 10 such books will be Rs. 90

Step-by-step explanation:

Here the cost of 4 books is given to be Rs. 36

We have to find the cost of 10 such books

Let the cost of 10 such books be x

We will use the direct proportion, as number of books increases the price will also increase

cost of 4 books = 36

cost of 10 books = x

                       4x = 36 × 10

                       4x = 360

                         x = 360/4

                         x = 90
