Final answer:
The list price of the article is Rs. 276.11
Step-by-step explanation:
To find the list price of the article, we need to first determine the original price before the discount was applied.
We can use the formula:
List price = Sale price / (1 - Discount percentage)
Here, the sale price is Rs. 248.50 and the discount is 10%.
Substituting these values into the formula:
List price = 248.50 / (1 - 0.10)
= 248.50 / 0.90
= Rs. 276.11
