A pair of articles was bought for Rs. 1,820 at a discount of 20%, and marked price of each article is same. What is the marked price (in Rs.) of an article?

Correct option is A

Given:
Cost Price of a pair of articles = ₹1,820
Discount = 20%
Marked Price of each article is the same.
Formula Used:
​$$\text{Marked Price} = \dfrac{\text{Cost Price}}{1 - \dfrac{\text{Discount}\%}{100}}\\\text{Total Marked Price} = 2 \times \text{Marked Price of one article}$$​​
Solution:
Total Marked Price =$$\dfrac{1820}{1 - \dfrac{20}{100}} \\$$​​

Total Marked Price = $$\dfrac{1820}{1 - 0.2} \\$$​

Total Marked Price = $$\dfrac{1820}{0.8} = 2275 \\$$​​
Marked Price of one article = $$\frac{₹2,275} 2$$​= ₹1,137.50
The marked price of an article is ₹1,137.50.
