A person bought a laptop for $\text{Rs. }40,000$ and sold it at a profit of $15\%$. What is the selling price of the laptop?

Given parameters:
* Cost Price ($\text{CP}$) = $\text{Rs. }40,000$
* Profit Percentage = $15\%$

The formula to calculate the Selling Price ($\text{SP}$) is:

$$\text{SP}=\text{CP}\times \left(1+\frac{\text{Profit Percentage}}{100}\right)$$

Substitute the given values into the formula:

$$\text{SP}=40000\times \left(1+\frac{15}{100}\right)$$

$$\text{SP}=40000\times \frac{115}{100}$$

$$\text{SP}=400\times 115$$

$$\text{SP}=\text{Rs. }46,000$$

Thus, the selling price of the laptop is $\text{Rs. }46,000$.
