Answer:
<h3>33.3%</h3>
Explanation:
profit percent = Sp-Cp/Cp * 100%
Sp is the selling price
Cp is the cost price
Let the selling price of the article be x
If it is sold with a profit of 25% of selling price, then;
Profit = 0.25x
Since Profit = Sp - Cp
0.25x = x - Cp
Cp = x - 0.25x
Cp = 0.75x
Substitute into the formula
Profit percent = 0.25x/0.75x * 100
Profit percent = 0.25/0.75 * 100
Profit percent = 1/3 * 100
Profit percent = 33.3%
Hence the profit percent is 33.3%
