### What is Meant by Percentage Decrease?

In Mathematics, the percentage decrease is defined as the change in percentage in which something loses its value. The percentage decrease can be calculated by dividing the decreased value by the original value and then multiplied by 100. Thus the percentage decrease formula is given by

Percentage Decrease = (Decreased Value / Original Value)× 100

Here, Decreased value = Original Value – New Value.

For example, the original price of the pen is Rs. 50. But the selling price of the pen is Rs, 45, then the percentage decrease is calculated as

Decreased price = 50-45 = 5

Then, the percentage decrease = (5/50)× 100 = 10%
