-A shopkeeper bought an article marked it 80% above the
cost price and sold it after giving a discount of 25%. Had he bought it for Rs 400 less and sold it for Rs. 175 more, then he would have made a profit of Rs. 1200. Find the cost price of the article.Solution
Let the cost price of the article be Rs. 100x Marked price of the article = 1.8 × 100x = 180x The selling price of the article = 0.75 × 180x = 135x According to the question. (135x + 175) – (100x –400) = 1200 35x = 625 x= 625/35= 17.85 then the cost price of article 100×17.85=1785rs
