The formula to calculate the Discount Ratio (DR) is:
\[ DR = \left( \frac{D}{OP} \right) \times 100 \]
Where:
The Discount Ratio (DR) is the percentage of the total discount relative to the original price. It is calculated by dividing the total discount by the original price and then multiplying by 100. This gives the discount as a percentage of the original price.
Let's assume the following values:
Step 1: Calculate the Discount Ratio (DR):
\[ DR = \left( \frac{20}{100} \right) \times 100 = 20\% \]
The discount ratio is 20%.
