If the selling price is Rs 75 and the cost price is Rs 60 then find the profit %. 

The profit percentage can be calculated by dividing the profit by the cost price and multiplying by 100:

$\mathrm{Profit}\%=\frac{\mathrm{Profit}}{\mathrm{Cost} \mathrm{price}}\times 100$

Profit is the difference between the selling price and the cost price:

Profit = Selling Price - Cost Price

Given, the selling price = Rs. 75 and the cost price = Rs. 60.

Profit = Rs. 75 - Rs. 60 = Rs. 15

$\mathrm{Profit}\%=\frac{15}{60}\times 100$

$\mathrm{Profit}\%=25\%$.
