Hello,
Got a trouble with the percentage in SQL. To be more precise, it is required to take a certain percentage off of a row in the column. For example (taking 40% of the row's amount). Any help will be appreciated. Thanks.

What I have tried:

I tried different queries and subqueries but none of them gives the desired result.
