Question 9

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 %
