suppose this number is 100
then it is increase 20℅ it number will be there 120
then 120 decrease the 15 %
120-[120×15/100]
120-18= 102
102-100=2
therefore we can call that this number is increase 2 %
then it is increase 20℅ it number will be there 120
then 120 decrease the 15 %
120-[120×15/100]
120-18= 102
102-100=2
