Question
Ravi marked an item at 125% above
its cost price and then sold it after applying three successive discounts of 20%, 20%, and 25%. Calculate the profit or loss percentage Ravi incurred in this transaction.Solution
ATQ,
Let the cost price of the item = Rs. 100 So the marked price of the item = 100 × 2.25 = Rs. 225 So the selling price of the item = 225 × 0.80 × 0.80 × 0.75 = Rs. 108 So the profit percent = {(108 – 100)/100} × 100 = 8%
