Correct Answer: 10%
Solution : Total cost = (Quantity of first variety × Cost per kg) + (Quantity of second variety × Cost per kg) ⇒ Total cost = (20 kg × Rs.30) + (20 kg × Rs.30) = Rs. 600 + Rs. 600 = Rs.1200 ⇒ Total selling price = (Total quantity × Selling price per kg) = (40 kg × Rs.33) = Rs.1320 ⇒ Profit = Total selling price − Total cost = Rs.1320 − Rs.1200 = Rs.120 Using the formula, Percentage of profit = $\frac{\text{Profit}}{\text{Total cost}}×100$ ⇒ Percentage of profit = $\frac{120}{1200}$ × 100 = 10% Hence, the correct answer is 10%.
