.

Let X be the original price.


Then the 20% reduced price is 0.8X.


To restore 0.8X to X, you need to add one fourth of 0.8X to 0.8X.


It means that you need to increase 0.8X by 25%.


ANSWER.  The reduced price must be increased by 25%.

Looking into the Alan's questions, I think that they all are irrelevant to the problem.

By the way, Alan, couple of days ago you were going to solve the problem from the post, related to the "L5 in 95" movement.

Do you have any progress in it ? ?

Why would anyone selling anything do that?
Or be concerned about "restoring it to its OP?"
