If the cost of 4 pencils is Rs 8, find the cost of 7 pencils.

Answer

To solve the problem of finding the cost of 7 pencils when the cost of 4 pencils is Rs 8, we can follow these steps:

### Step 1: Find the cost of one pencil.
We know that the cost of 4 pencils is Rs 8. To find the cost of one pencil, we divide the total cost by the number of pencils.

\[ \text{Cost of one pencil} = \frac{\text{Total cost of 4 pencils}}{\text{Number of pencils}} = \frac{8 \text{ Rs}}{4} = 2 \text{ Rs} \]

### Step 2: Calculate the cost of 7 pencils.
Now that we know the cost of one pencil is Rs 2, we can find the cost of 7 pencils by multiplying the cost of one pencil by the number of pencils.

\[ \text{Cost of 7 pencils} = \text{Cost of one pencil} \times \text{Number of pencils} = 2 \text{ Rs} \times 7 = 14 \text{ Rs} \]

### Final Answer:
The cost of 7 pencils is Rs 14.
