Question
A sold an article at 45% profit. If the profit earned
had been 228% more, then the profit percentage would have been numerically equal to CP. Find the actual cost price of the article.Solution
Let the cost price of the article be Rs. 100x Therefore, selling price of article = Rs. 145x Therefore, profit earned = 145x – 100x = Rs. 45x New profit = 3.28 × 45x = Rs. 147.6x According to the question, (147.6x/100x) × 100 = 100x Or, x = 1.476 Therefore, actual cost price = 100x = Rs. 147.6
