Question 46(ii)
The cost of a notebook is Rs. 10. Draw a graph after making a table showing the cost of 2,3,4..... notebooks. Use it to find the number of notebooks that can be purchased with Rs. 50.

Answer 1

Let, x be number of notebooks
and y be the cost of a notebook

$\begin{array}{ccccccccc}x& 1& 2& 3& 4& 5& 6& 7& 8\\ y& 10& 20& 30& 40& 50& 60& 70& 80\end{array}$



The number of notebooks that can be purchased with Rs.50 is equal to the abscissa of the point (5,50).
Hence, 5 notebooks can be purchased with Rs.50.
