3. A trader mixes 2 kg of butter which costs PKR 80 per kg with 3 kg of butter which costs PKR 60 per kg . He sells the mixture at PKR 25.5 per 250 g . Express his profit as a percentage of his selling price.

To find the profit as a percentage of the selling price, we first need to calculate the total cost of the mixture and the total selling price. Given: - 2 kg of butter at PKR 80 per kg - 3 kg of butter at PKR 60 per kg - Selling price of the mixture at PKR 25.5 per 250 g Let's calculate the total cost of the mixture and the total selling price: 1. Calculate the total cost of the mixture: - Cost of 2 kg of butter at PKR 80 per kg = 2 kg * PKR 80/kg = PKR 160 - Cost of 3 kg of butter at PKR 60 per kg = 3 kg * PKR 60/kg = PKR 180 - Total cost of the mixture = PKR 160 + PKR 180 = PKR 340 2. Calculate the total selling price: - Since the selling price is given per 250 g, we need to convert the total weight of the mixture to grams. - Total weight of the mixture = 2 kg + 3 kg = 5 kg = 5000 g - Total selling price = 5000 g * PKR 25.5/250 g = PKR 510 Now, we can calculate the profit as a percentage of the selling price: Profit = Total selling price - Total cost of the mixture Profit percentage = (Profit / Total selling price) * 100 Let's calculate the profit and profit percentage. Calculate the value by following steps: - step0: Calculate: \(\frac{\left(510-340\right)}{510}\times 100\) - step1: Remove the parentheses: \(\frac{510-340}{510}\times 100\) - step2: Subtract the numbers: \(\frac{170}{510}\times 100\) - step3: Reduce the fraction: \(\frac{1}{3}\times 100\) - step4: Multiply: \(\frac{100}{3}\) The profit as a percentage of the selling price is 33.33%.
