Percentage Reduction Formula

The percentage reduction formula is the ratio of the reduction in the quantity to its initial value multiplied by 100. Since the percentage has to be a positive quantity, we take the absolute value of the initial value. i.e., From the previous example, Reduction in business-1 = 15000 - 10000 = $5000. Reduction in business-2 = 35000 - 30000 = $5000.
