You can put this solution on YOUR website!
to make the calculations simple you can assume the price of the product be 100$
now the price is reduced by 30%, so the new price is 100-30% of 100
that is 100-30=70$
now to bring it back to 100% that is 100$ we have to increase by 30
so the percentage increase will be 30/70 *100 = 300/7=42.85
so the percentage it should be increased to make it 100% is 42.85%
