PLEASE MARK MY ANSWER AS BRAINLIEST

Let the price of some merchandise is Rs.100.

If we apply 10% discount on it, it will become Rs.90.

Now if we again apply 20% discount then it will become Rs. 72.

So, overall discount = [(Marked Price - Total final price)/Marked price]*100

                                  = [(100-72)/100]*100

                                  = 28%
