Reverse percentages

Step 1 - Either add or subtract the percentage given in the problem from 100% to determine what percentage we have.

Step 2 - Find 1% by dividing by the percentage found in the previous step.

Step 3 - Find 100%(original amount) by multiplying your answer in step 2 by 100.

For example, If you have to work out the original price of a laptop that is being sold at 25% off:

1. work out the current price as a percentage of the original price so 100 - 25 = 75%

2. find 1% by dividing the current price by 75

3. Multiply this 1% by 100 to find the original price.
