A shop has a 20% of sale.  On the final day of the sale prices are reduce by 25%.

 

What is the overall percentage reduction?

 

No price figures have been given in the question only percentages

If I understand your question!

 

Take an item worth $100. Discount this by 20% and you would get:

$100 x 0.8 = $80. Now, if the additional discount of 25% is in addition to the initial discount of 20%, then you would have this:

$80 x 0.75 = $60 - the final price of the $100 item on the last day of sale. So, the overall sale rate would be: 100 - 60 = 40%.
