Cost price of the oil = (3/4)×C.P of first oil + (1/4)×C.P second oil = (3/4)×180+(1/4)×220 = 135 + 55 = Rs. 190 per kg ⇒ Selling price of the oil = Rs. 210 per kg ∴ Profit on 1 kg of oil = S.P – CP = 210 – 190 = Rs. 20 Profit percentage = [Profit/(C.P)]×100 = (20/190)×100 = (20/19)×10 ≃ 10.5%Related questions
