The Banker's Rule uses____?*1 pointuses ordinary interestuses exact interestuses both ordinary and exact interestnone of the above

The Banker's Rule, also known as the Banker's Method, primarily uses ordinary interest. This method calculates interest based on a 360-day year rather than the more common 365-day year used in exact interest calculations. In the context of banking and finance, the ordinary interest calculation simplifies computations and is widely accepted for short-term interest calculations. While the Banker's Rule does not use exact interest directly, it's important to note that the terms "ordinary" and "exact" interest refer to the methods of calculating interest based on different day conventions. Therefore, the correct answer to the question is:

uses ordinary interest.
