The profit earned after selling an article for Rs.1643
is the same as loss incurred after selling the article for Rs.1121. What is the cost price of the article?Solution
Let CP = Rs. x Profit = Rs. y Therefore, x + y = SP => x + y = 1643 ----- (i) When SP = Rs. 1121, the loss = Rs. y Therefore, x – y = 1121 ------- (ii) Solving both the equation, we get => 2x = 2764 => x = Rs. 1382
