Given Information: Marked Price (MP) of the article = Rs. 4000
Profit earned by the shopkeeper = Rs. 550
Cost Price (CP) of the article = Rs. 2250
Calculating Selling Price (SP):
We know that Profit = SP - CP.
Therefore, the Selling Price can be calculated as: SP = CP + Profit
SP = 2250 + 550
SP = 2800
Calculating Discount:
Discount is the difference between the Marked Price and the Selling Price:
Discount = MP - SP
Discount = 4000 - 2800
Discount = 1200
Calculating Percentage Discount:
Percentage Discount is calculated using the formula:
Percentage Discount = (Discount / MP) * 100
Percentage Discount = (1200 / 4000) * 100
Percentage Discount = 30%
So, the percentage discount on the article is 30%
