Answer:

There are 7 ways in which a person can spend exactly Rs. 1000 to buy pens and notebooks.

Step-by-step explanation:

Given : A pen costs Rs.11 and a notebook costs Rs.13.

To find : The number of ways in which a person can spend exactly Rs. 1000 to buy pens and notebooks?

Solution :

Let X be the number of pen.

Let y be the number of notebook.

According to question,

A pen costs Rs.11 and a notebook costs Rs.13.

i.e. Total COST $11x+13y$

A person spend exactly Rs.1000.

Therefore, The required EQUATION form is $11x+13y=1000$

or $x=\frac{1000-13y}{11}$

Now, For different value y there is different value of x.

y 5 16 27 38 49 60 71

x 85 72 59 46 33 20 7

Hence, There are 7 ways in which a person can spend exactly Rs. 1000 to buy pens and notebooks.
