Answer 2

Answer:

The cost of 8 books will be RS. 1280

Step-by-step explanation:

Here the cost of 10 books is given to be Rs. 1600

We will first find out the cost of 1 book

cost of 10 books = 1600

cost of 1 book = 1600/10

                       = 160

Now, we will find the cost of 8 books

cost of 8 books =  8 × cost of 1 book

                         = 8 × 160

                          = 1280
