The given bar graph shows the marked price of five different products in a showroom:


If the marked price of the laptop is $15\%$ more than its cost price and the shopkeeper offers a discount of $10\%$ on the marked price of the laptop, then find the profit $\%$ of the laptop.

Let the Cost Price ($\text{CP}$) of the laptop be $100$.
Since the Marked Price ($\text{MP}$) is $15\%$ more than the $\text{CP}$:

$$\text{MP}=100\times \left(1+\frac{15}{100}\right)=115$$

The shopkeeper offers a $10\%$ discount on the $\text{MP}$. Thus, the Selling Price ($\text{SP}$) is:

$$\text{SP}=\text{MP}\times \left(1-\frac{10}{100}\right)=115\times 0.9=103.5$$

The profit percentage is calculated as:

$$\text{Profit }\%=\left(\frac{\text{SP}-\text{CP}}{\text{CP}}\right)\times 100$$

$$\text{Profit }\%=\left(\frac{103.5-100}{100}\right)\times 100=3.5\%$$

*(Note: The absolute value of $\text{Rs.15000}$ from the bar graph is not necessary to compute the percentage profit.)*
