Question

What single percentage change is equivalent to a 11% increase followed by a 13% increase?

Answer 1

The equivalent percentage change is
`25.43` %

Explanation:

Let there be a number 100

It is first increased 11 % , so the new number would be
`100 + 11`% of 100

i.e
`100 + 11 = 111`

Now, this number 111 is further increased by 13 % so the new number is
`111 + 13`% of 111

125.43

So , the total increase or equivalent increase is

`(125.43-100)/(100) *100\\= 25.43`%
