Question
Anita sold an article at 50% profit. If the profit
percentage had been numerically equal to CP, then the profit earned would have been 300% more. Find the amount for which Anita sold the article originally.Solution
ATQ, Let the cost price of the article be Rs. 100x. Selling price = Rs. 150x. Original profit = 150x - 100x = Rs. 50x. New profit = 4 × 50x = Rs. 200x. According to the question, 
x = 2. Therefore, the original selling price = 150x = Rs.300
