In questions dealing with percentages, it is helpful to start with 100 as the initial number

Let us assume original price was 100
During sale it's lowered by 20% -> so price becomes -> 80
Now, it was further reduced by 10%. This 10% is of the current price, and not original price.
So new price -> 80 - (10% of 80) = 72
Now the question asks, what percent of discount could have been applied on the original price (100) to get directly to the latest price (72)
Answer is easy -> 100 -72 = 28
