Hey @7560e065, if you reduce a bank account by 50% and then increase it by 50%, the account holder will end up with 75% of the original amount. This is because reducing the account by 50% leaves the account holder with 50% of the original amount. Then, increasing it by 50% of that 50% adds 25% of the original amount back, resulting in a total of 75% of the original amount.
