If 6 notebooks cost Rs 45, how much would 8 notebooks cost ?

Answer

To solve the problem of finding the cost of 8 notebooks when 6 notebooks cost Rs 45, we can follow these steps:

### Step 1: Find the cost of 1 notebook.
To find the cost of one notebook, we divide the total cost of 6 notebooks by the number of notebooks.

\[ \text{Cost of 1 notebook} = \frac{45 \text{ Rs}}{6} = 7.5 \text{ Rs} \]

### Step 2: Calculate the cost of 8 notebooks.
Now that we know the cost of one notebook, we can find the cost of 8 notebooks by multiplying the cost of one notebook by 8.

\[ \text{Cost of 8 notebooks} = \text{Cost of 1 notebook} \times 8 = 7.5 \text{ Rs} \times 8 \]

### Step 3: Perform the multiplication.
Now, we will calculate the total cost for 8 notebooks.

\[ 7.5 \text{ Rs} \times 8 = 60 \text{ Rs} \]

### Final Answer:
Thus, the cost of 8 notebooks is Rs 60.
