An article is at 10% more than the CP. If a discount of 10% is allowed, then which of the following is correct?

Correct option is B

Cost Price (CP): The original price of the article.
Selling Price (SP): The price at which the article is sold.
Marked Price (MP): The price at which the article is initially listed (before any discounts).
The article is marked 10% more than the CP.
If CP = 100, then MP = 100 + (10/100) x 100 = 110
A discount of 10% is given on the MP.
SP = MP - (10/100) x MP = 110 - (10/100) x 110 = 110 - 11 = 99
Since SP (99) is less than CP (100), there is a loss.
Loss = CP - SP = 100 - 99 = 1
Loss Percentage = (Loss/CP) x 100 = (1/100) x 100 = 1%
