Let us suppose the price of certain item gets reduces. To calculate its reduction rate we need to study the percentage decrease. The Percentage decrease is calculating the reduce in value in percentage when the price of certain item is decreased by specific amount.
The percentage decrease is given by
Percentage Decrease Calculator is a online tool used to calculate the percentage decrease. It is a easy way to get the idea to what rate the reductions are taking place. You just have to enter the actual amount and decreased amount in the blocks provided to get to know decrease rate.
Below are mentioned the Steps to Calculate the Percentage decrease:
Step 1 : Go through the problem and note down the Actual price and decreased price of the item.

Step 2 : To find the Percentage decrease use the formula
Percentage Decrease = $\frac{Actual\ amount\ -\ Decreased\ amount}{Actual\ amount}$ $\times$ 100 %
Put the values in the formula and get the answer.
Let us go through some solved problems on percentage decrease.

Solved Examples

Question 1: A bike having a price of Rs 50000 is kept on sale for Rs 46750. Calculate the percentage decrease.
Solution:
 
Given: Actual amount = 50000 Rs and Reduced amount = 46750 Rs
Reduce in amount = 50000 - 46750 = 3250
The Percentage decrease is given by
Percentage decrease = $\frac{Actual\ amount\ -\ decreased\ amount}{Actual\ amount}$ $\times$ 100 %

                                = $\frac{50000 - 46750}{50000}$ $\times$ 100%

                                = $\frac{3250}{50000}$ $\times$ 100 %

                                = 0.065 $\times$ 100 %
                                = 6.5 %.
The percentage decrease is 6.5%.

 

Question 2: The price of petrol per liter is Rs 80 is being reduced to Rs 75. Calculate its percentage decrease.
Solution:
 
Given: Actual amount = 80 Rs and  Reduced amount = 75 Rs
Reduce in amount = 80 - 75 = 5
The Percentage decrease is given by
Percentage decrease = $\frac{Actual\ amount\ -\ decreased\ amount}{Actual\ amount}$ $\times$ 100 %

                                = $\frac{80 - 75}{80}$ $\times$ 100%

                                = $\frac{5}{80}$ $\times$ 100 %

                                = 0.0625 $\times$ 100 %
                                = 6.25 %
The percentage decrease in petrol is 6.25 %.
