Answer:

Increase:

It will have increase when y>x

so, percentage of increase is


=(y-x)/(x)* 100

Decrease:

It will have decrease when x>y

so, percentage of decrease is


=(x-y)/(x)* 100

Explanation:

Let's assume initial value as x

assume final value as y

Increase:

It will have increase when y>x

so, percentage of increase is


=(y-x)/(x)* 100

For example:

Initial value is 40

So, x=40

Final value is 50

so, y=50

now, we can find percentage in increase


=(50-40)/(40)* 100


=25

Decrease:

It will have decrease when x>y

so, percentage of decrease is


=(x-y)/(x)* 100

For example:

Initial value is 50

So, x=50

Final value is 40

so, y=40

now, we can find percentage in decrease


=(50-40)/(40)* 100


=25
