Let's assum that the original price was !00.

With a 20% sale (100 x 0.20  =  20), the sale price is 100 - 20  =  80.

Now, there is a further 25% off (80 x 0.25  =  20), so the final price is 80 - 20  =  60.

The total off is 100 - 60  =  40.

40 off from 100 is a percentage of 40/100  =  0.40  =  40%
