Calculate Percentage of Discount

If you know the original cost and sale cost,


apply the following formula to calculate Percentage of the Discount


Formula : 


(OriginalPrice-SalePrice)/OriginalPrice*100 = ? % Discount


Example :
OriginalPrice = 2500
SalePrice = 2000
(2500-2000)/2500 = 0.2
0.2*100 = 20 %


So 20 % is the Discount value.
