Answer 2

Answer:

You can find the cost price of the article easily by letting it 100% and also by understanding that here Rs.10 is a difference between first and second selling price of the article because second time he is selling the article for Rs.10 more.

First time he is selling the article at 10% profit means at 110%.

Second time he bought it at 20% less then before means at (100–20)= 80% and sold it for Rs.10 more or at the profit of 40%.
