we will take the number as 100
then 20% of 100 is
20
then, if we increase the number by 20% then it will become 120
and then if we decrease the number by 20% it is 80
if we subtract those two number
120-80
40
decrease by 4%
then 20% of 100 is
20
then, if we increase the number by 20% then it will become 120
and then if we decrease the number by 20% it is 80
if we subtract those two number
120-80
40
decrease by 4%
