Hi all

It may be sounds foolish but i have a question

100-------------------------120

now 20% increase at year 1 gives 120 ---------100*1.2=120

if we know that year 2 is 120 and there is % age decrease 20% then ------------

20 % decrease means 80% is left so

0.8* 120= 96

or

120/1.2 =100

which one is correct and why
