Question: If an article is sold for Tk. 540 at a loss of 10%, what should be its selling price in order to earn a profit of 15%?

Solution:
Selling Price of the article = Tk. 540
Loss % = 10%

∴ Cost Price = {100/(100 - 10)} × 540
= (540 × 100)/90 = 600

Now, Cost Price = Tk. 600 and Profit% = 15%
∴ New Selling Price = {(100 + 15)/100} × 600 = (115 × 600)/100
= 690 Tk.

Therefore, the article should be sold at Tk. 690
