take an example 100.
In 100 20% means 20...
20% increased means 100+20=120
in 120 15% means 18...
then 15% decreased means 120-18=102.
so the net increase is 2%
In 100 20% means 20...
20% increased means 100+20=120
in 120 15% means 18...
then 15% decreased means 120-18=102.
so the net increase is 2%
