To find the price of one pen, you can use the formula:

$\text{Price of one pen} = \frac{\text{Total Price of 13 pens}}{\text{Number of pens}}$

Given:

• Total price of 13 pens = Rs 260
• Number of pens = 13

So,

$\text{Price of one pen} = \frac{260}{13} = 20$

Thus, the price of one pen is Rs 20.
