Answer 1

Answer:

hope it helps :)

Step-by-step explanation:

Total cost of 10 books = Rs. 120

Total cost of 8 books = Rs. 94

⇒ The cost of 2 books = Rs. 26

Let the price of each book be x and y.

⇒ x + y = 26 - - - - - - (1)

(160100)x+y=26

On Solving for y, we get

y = 10

Now, Substituting y = 10 in (1) we get,

x + 10 = 26

x = 16

So the price of each book is Rs. 16 and Rs. 10 respectively.
