Let the selling price per chair = ₹1 unit (assumption for simplicity).
Given:
Number of chairs sold = 152
Total selling price = 152
Gain = selling price of 52 chairs = 52
Find total cost price
Cost Price=Selling Price−Gain
=152−52=100
Calculate profit percentage
Profit %=Cost PriceGain×100
=10052×100
= 52%
