Question
A sold an article at 40% profit. If the profit earned
had been 220% 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. 140x Therefore, profit earned = 140x β 100x = Rs. 40x New profit = 3.2 Γ 40x = Rs. 128x According to the question, (128x/100x) Γ 100 = 100x Or, x = 1.28 Therefore, actual cost price = 100x = Rs. 128
