Answer:
Increase:
It will have increase when y>x
so, percentage of increase is
Decrease:
It will have decrease when x>y
so, percentage of decrease is
Step-by-step 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
For example:
Initial value is 40
So, x=40
Final value is 50
so, y=50
now, we can find percentage in increase
Decrease:
It will have decrease when x>y
so, percentage of decrease is
For example:
Initial value is 50
So, x=50
Final value is 40
so, y=40
now, we can find percentage in decrease
