If 6 note boks cost Rs. 45, how much would 8 note books 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-by-step Solution:

1. **Find the cost of one notebook**:
- We know that the cost of 6 notebooks is Rs. 45.
- To find the cost of one notebook, we divide the total cost by the number of notebooks:
\[ \text{Cost of 1 notebook} = \frac{45}{6} \]
- Calculating this gives:
\[ \text{Cost of 1 notebook} = 7.5 \text{ Rs.} \]

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:
\[ \text{Cost of 8 notebooks} = 8 \times \text{Cost of 1 notebook} \]
- Substituting the value we found:
\[ \text{Cost of 8 notebooks} = 8 \times 7.5 \]
- Calculating this gives:
\[ \text{Cost of 8 notebooks} = 60 \text{ Rs.} \]

### Final Answer:
The cost of 8 notebooks is Rs. 60.
