Answer 2

Answer:

The cost of 9 note book is Rs.72

Step-by-step explanation:

According to the details provided in the above question,

The given data is cost of 4 notebooks is Rs.32

We have to find the cost of 9 notebook.

Here to get the cost of one note book we have to divide the cost of 4 notebook divided by 4,

Given, 4 notebook = Rs.32

Cost of 1 note book is,

$=\frac{32}{4} \\=Rs.8$

The cost of 1 note book is Rs.8

So, the cost of 9 notebook is,

$=9\times 8\\=Rs.72$

Hence the cost of 9 notebook is Rs.72
