Question
A retailer increased the price of a gadget by 35%
relative to its cost price. If the gadget is sold at a 25% discount, determine the retailer's gain percentage.Solution
ATQ,
Let the cost price of the gadget be Rs. '120c'
So, marked price = 120c * 1.35 = Rs. '162c'
So, selling price = 162c * 0.75 = Rs. '121.5c'
So, required gain percentage = {(121.5c - 120c)/120c} * 100 = 1.25%
