Question: If an article is sold for Tk. 356 at a loss of 11%, what should be its selling price in order to earn a profit of 11%?

Solution:
Selling Price of the article = Tk. 356
Loss % = 11%

∴ Cost Price = {100/(100 - 11)} × 356
= (356 × 100)/89 = 400

Now Cost Price = Tk. 400 and Profit% = 11%
∴ New Selling Price = {(100 + 11)/100} × 400 = (111 × 400)/100 = 444 Tk.

Therefore, the article should be sold at Tk. 444
