Question 51
The profit earned after selling an article for Rs. 878 is the same as loss incurred after selling the article for Rs. 636. What is the cost price of the article ?
Solution
Let the cost price of the article be x Rs. Profit earned by selling it at 878 = 878 - x
Loss incurred by selling the article for 636 = x - 636
But profit earned = loss incurred
So, 878 - x = x - 636
So, x = 757
