📊 Let’s Solve for x! 🤔

Step 1: Let’s assume the cost price of 1 article is Rs. y.

Then, the cost price of 20 articles is Rs. 20y.

Step 2: The selling price of x articles is equal to the cost price of 20 articles.

So, the selling price of x articles is also Rs. 20y.

Step 3: The profit is 25%, which means the selling price is 125% of the cost price.

For x articles, the cost price is Rs. xy.

Step 4: Set up the equation using the information from steps 2 and 3.

Selling price of x articles = 20y

1.25(xy) = 20y

Step 5: Solve for x.

1.25x = 20

x = 20 / 1.25

x = 16

The final answer is: x = 16 📈
