Answer 2

Given :-

The cost of a book and a notebook is 36.

The cost of the book is five times the cost of the notebook.

To find :-

The cost of the book.

Solution :-

Let the cost of a note book be Rs. X

=> X = 36/6

=> X = 6

Therefore, X = Rs. 6

The cost of a note book = Rs. 6

The cost of a book = 5(6) = Rs. 30
