let the cost of per kg rice be Rs y Let the amount of rice sold at 15% profit be m kg and so the rice sold at 20% loss be (600-m)kg selling price of m kg rice which is sold at profit = 1.15y per kg × m Selling price of (600-m) kg rice at 20% loss = 0.8y × (600-m) Over all loss is = 6% So,1.15my + 480y - 0.8my = 0.94×600y= 564y 84y = 0.35my m = 240 kg So amount of rice sold at 20% loss = 600-240 = 360 kg
