Answer:

Decrease by 20%.

Step-by-step explanation:

We have to find the percent of increase or decrease from n to $\frac{4}{5}n$ .

Now, $\frac{4}{5}n = 0.8n < n$

So there is a decrease fro n to $\frac{4}{5}n$ .

Now, the percentage of decrease will be given by

= $[ \frac{\textrm {Original Value - Final Value}}{\textrm {Original Value}}]\times 100 \%$

= $[ \frac{n - 0.8n}{n}]\times 100 \%$

= 20% (Answer)
