If a shopkeeper bears 25% loss, then which of the following statements is/are correct? 
Statement A: The cost price of 15 articles is equal to the selling price of 20 articles.
Statement B: The cost price of 12 articles is equal to the selling price of 17 articles.

Correct option is A

Given:

The shopkeeper bears a 25% loss.

Formula Used:​
If the loss percentage is x, then the relationship between cost price (CP) and selling price (SP) is:

SP $$= \text{CP} \times \left(1 - \frac{x}{100}\right)$$​

Solution :

For a 25% loss, the selling price is 75% of the cost price:

SP =$$\text{CP} \times \frac{75}{100} = \text{CP} \times 0.75$$​​

Statement A:

The cost price of 15 articles is 15 × CP.

The selling price of 20 articles is 20 × SP = 20 × 0.75 × CP = 15 × CP

Statement A is correct.

Statement B:

The cost price of 12 articles is 12 × CP.

The selling price of 17 articles is 17 × SP = 17 × 0.75 × CP = 12.75 × CP

Statement B is incorrect because the cost price of 12 articles is not equal to the selling price of 17 articles.

Thus, Statement A is correct, and Statement B is incorrect.
