Question
A discount of Rs. 1800 is offered on a washing machine,
which is Rs. 700 less than the profit made on selling it. If the cost price is Rs. 2000, find the mark-up percentage.Solution
ATQ,
Given, Discount = Rs. 1800, Cost price = Rs. 2000
Also, profit earned = 1800 + 700 = Rs. 2500
Selling price = 2000 + 2500 = Rs. 4500
So, Marked price = 4500 + 1800 = Rs. 6300
So, required percentage = {(6300 - 2000) /2000} × 100 = 215%
