Answer 1

Answer:

What is the net increase or decrease percent? ... As per the second case, resultant number is then decreased by 20% ... So, we can see that we have a 4 percent over all decrease.

Answer 2

Answer:

The net decreased percent is 4%.

Step-by-step explanation:

Let the number be 100

Increased number =100+20/100×100=120

When decreased by 20%,the number =120-20/100×120=96

Therefore, decreased %=(100-96)=4%
