Question
A sold an article at 25% profit. If the profit earned
had been 320% 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. 125x Therefore, profit earned = 125x – 100x = Rs. 25x New profit = 4.2 × 25x = Rs. 105x According to the question, (105x/100x) × 100 = 100x Or, x = 1.05 Therefore, actual cost price = 100x = Rs. 105
