Question
Quantity I: A shopkeeper sold an article for Rs.1500
and made a profit of Y%. If he increases the selling price by Rs.400, he can make a profit of (Y + 40)%. Find the value of Y. Quantity II: If the marked price of an article is Rs.3200 and the shopkeeper offers Y% discount, and the article is sold for Rs.2700, find the value of Y.Solution
Quantity I: The difference between the profit percentages = 40% 400 = 40% of the cost price 100% = Rs.1000 (Cost Price) Selling price = Rs.1500 Profit percentage Y = (1500 - 1000) × 100 / 1000 = 50% Quantity II: Marked price = Rs.3200 Selling price = Rs.2700 Discount = 3200 - 2700 = Rs.500 Discount percentage Y = 500 × 100 / 3200 = 15.625% Answer: C
