Let the price of a kg of low quality rice be Rs. T. ⇒ In 20 kg rice, 10 kg is of Rs. 80 per kg and remaining 10 kg is of Rs. T per kg. Cost price = 10 × 80 + 10 × T = 800 + 10T Sellin price = 20 × 80 = 1600 We know, Selling Price = Cost Price × (1 + Profit Percentage/100) ⇒ 1600 = (800 + 10T) × (1 + 33.33/100) = (800 + 10T) × (4/3) ⇒ 1600 = 3200/3 + 40T/3 ⇒ 4800 = 3200 + 40T ⇒ T = 1600/40 = 40 ∴ Price of 10 kg of low quality rice = 10 × Rs. 40 = Rs. 400Related questions
