12 articles were sold at the cost price of 15 articles .  Find the Profit % Options :30%20%25%none

The problem states that 12 articles were sold at the cost price of 15 articles. This means that the selling price of 12 articles is the same as the cost price of 15 articles.

Step 1: Let's assume the cost price of 1 article is $1. Therefore, the cost price of 15 articles is$15.

Step 2: The selling price of 12 articles is also $15 (as per the problem). Therefore, the selling price of 1 article is$15/12 = $1.25.

Step 3: The profit for 1 article is the selling price minus the cost price, which is $1.25 -$1 = $0.25.

Step 4: The profit percentage is calculated as (Profit/Cost Price) * 100. So, the profit percentage is ($0.25/$1) * 100 = 25%.

So, the profit percentage is 25%.
