The price of the goods increased by 10% from the original price, then decreased by 19%

The price of the goods increased by 10% from the original price, then decreased by 19% from the new price. How much has the starting price changed?

Let’s say the original price was 100 den.
The growth was 10%: 100 X 10% = 10 monetary units (percent of the number is calculated as follows: 100 X 10: 100 = 10).
As a result, the price increased to 110 monetary units.
Then there was a 19% drop in the increased price:
110 X 19% = 20.9 monetary units (110 X 19: 100 = 20.9 monetary units)
The price after the decline was: 110 – 20.9 = 89.1 monetary units.
Now let’s calculate how much the original price has changed: 100 – 89.1 = 10.9 monetary units.
Find the percentage of the change from the original price: 10.9: 100 X 100 = 10.9%.
Those. the original price decreased by 10.9%.
Answer: a decrease of 10.9%.
