Answer :

The percentage increase of a given quantity from 20 to 40 is 100%.

Original quantity = 20

New quantity = 40

In order to calculate the percentage increase, one had to subtract the original quantity from the new quantity and then divide the value by the original quantity. This will be:

= (New quantity - Original quantity) / Original quantity × 100

= (40 - 20) / 20 × 100

= 20/20 × 100

= 1 × 100

= 100%

Therefore, the percentage increase of the quantity from 20 to 40 is 100%.
