A trader mixes three varieties of groundnuts costing Rs. 50, Rs. 20 and Rs. 30 per kg in the ratio 2 : 4 : 3 in terms of weight and sells the mixture at Rs. 33 per kg. What percentage of profit does he make?

Solution & Step-by-step Explanation

Let the weights of the three varieties be 2 kg, 4 kg, and 3 kg respectively. Total weight of the mixture = 2 + 4 + 3 = 9 kg . Total Cost Price (CP) of the mixture: CP = (2 \times 50) + (4 \times 20) + (3 \times 30) CP = 100 + 80 + 90 = Rs. 270 Total Selling Price (SP) of the mixture: SP = 9 \times 33 = Rs. 297 Profit earned: Profit = SP - CP = 297 - 270 = Rs. 27 Profit percentage: Profit % = (\frac{Profit}{CP}) \times 100 = (\frac{27}{270}) \times 100 = 10%
