Two types of rice costing Rs.38 per kg and Rs.42 per kg are mixed in equal quantities and sold at Rs.45 per kg. Find the gain per cent.
Cost of 1 kg rice1 = Rs. 38 per kg
Cost of 1 kg rice2 = Rs. 42 per kg
Total quantity of rice = 1 + 1 = 2
Cost of 2 kg rice = Rs. 80
Selling price of the new mixture = Rs. 45 per kg
selling price of 2 kg rice = 2*45 = Rs. 90
profit = 90 - 80 = Rs. 10
profit = Rs. 10
profit% = $$\frac{profit}{cp}100$$
profit% =$$\frac{profit}{cp}100$$
= 12.5 %
