Question
A sold an article at 30% profit. If the profit earned
had been 310% 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. 130x Therefore, profit earned = 130x – 100x = Rs. 30x New profit = 4.1 × 30x = Rs. 123x According to the question, (123x/100x) × 100 = 100x Or, x = 1.23 Therefore, actual cost price = 100x = Rs. 123
