There are two ways to obtain the answer.

1) Find 10920 as a percentage of 12000 and ascertain the difference between this percentage and 100% to determine the reduction percentage.

100 x 10920/12000 = 91% : 100 - 91 = 9. Therefore the sale reduction = 9%.

2) Calculate the price reduction and then find what percentage this is of the original price. The answer is the sale reduction percentage.

12000 - 10920 = 1080.

100 x 1080/12000 = 9
