A shopkeeper allows his customers 10% off on the marked price of goods and still gets a profit of 25%. What is the actual cost to him of an article marked Rs 250?

Explanation

To solve the problem step by step, we need to find the actual cost price (CP) of an article that is marked at Rs. 250, given that the shopkeeper allows a 10% discount and still makes a profit of 25%.

### Step 1: Calculate the Selling Price (SP) after Discount
