Soln:Let S be the selling price of 1 article.Therefore, the selling price of 80 articles = 80 S The profit earned by selling these 80 articles = selling price of 50 articles = 50 S We know that Selling Price (S.P.) = Cost Price (C.P) + Profit ofSelling price of 80 articles = 80 S and Profit = 50 S 80 S = C.P + 50 S. Hence, C.P = 80 S - 50 S = 30 S.Profit %=(50S30S)×100=166.67%
