The profit earned by selling an article for Rs. 900 is double the loss incurred when the same article is sold for Rs. 450. At what price should it be sold to make a 25% profit?
Correct Answer: Option A
Explanation:
Let the cost price be CP. Profit = 900 - CP. Loss = CP - 450. Given: 900 - CP = 2 * (CP - 450). 900 - CP = 2CP - 900. 3CP = 1800, so CP = 600. For a 25% profit, Selling price = 1.25 * 600 = Rs. 750.
