The percentage profit earned by selling an article for Rs. 1920 is equal to the percentage loss incurred by selling the same article for Rs. 1280.
At what price should the article be sold to make 25% profit?
Let CP be x
1920-x / x = x-1280 / x
x = 1600
% profit = (gain / x) * 100
25 = (gain / 1600) * 100
gain = 400
The article must be sold at 1600+400=Rs. 2000
