Answer 2

Ram must sell rice at Rs. 10.4 per kg to earn a profit of Rs. 3/kg.

• Ram mixes 15 kg of sugar purchased at the rate of Rs. 8 with 25 kg of sugar purchased at Rs. 10 per kg.

• Total quantity of rice purchased = 25 + 25 = 50.

• Total cost in buying the rice = 15 × 8 + 25 × 10= 120 + 250 = Rs. 370.

• Now we have to find the selling price in which Ram should sell so that earns a profit Rs. 3 per kg.

• Now , the price of 1 kg of rice without any profit after mixing bot will be:

• Cost of 1 kg of rice after mixing = 370/50 = 7.4 Rs./kg

• Now Ram has to earn of profit of Rs. 3 per kg.

• Therefore , rate of 1 kg rice = 7.4 + 3 = 10.4 Rs./kg
