Question
The profit earned when an article is sold for Rs. 2,200
is the same as the loss incurred on selling it for Rs. 1,400. Find the selling price of the article if it is sold at a profit of 30%.Solution
ATQ, Let the cost price of the article be Rs. 'C'. So, 2,200 − C = C−1,400 Or, 2C = 3,600 So, C = 1,800 Therefore, selling price of the article at a profit of 30% = 1.30×1,800 = Rs.2,340
