# Use the exact interest method (365 days) and the ordinary interest method (360 days) to compare the amount of interest for the following loans.Principal Rate(%) Time(days) Exact Interest Ordinary Interest $486,000 13 1 2 127 _________ _________ To determine To calculate: The amount of interest accrued by using the ordinary method and the exact method on a principle amount of$486,000 at a rate of interest of 1312% and over a period of time of 127 days.

Explanation

Given Information:

The principle amount of $486,000 is made for 127 days at a rate of interest of 1312% . Formula used: The formula to compute the simple interest is, I=P×R×T Where, P is the principal amount, I is the amount of interest, R is the rate of interest and T is the time-period. The ordinary interest for the given loan is; Time=Number of days of a loan360 The exact interest for the given loan is; Time=Number of days of a loan365 Calculation: As, the principle amount of$486,000 is made for 127 days at a rate of interest of 1312%.

For ordinary interest for the given loan is;

Time=Number of days of a loan360

Thus, T=127360

For exact interest for the given loan is;

Time=Number of days of a loan365

Thus, T=127365

The amount of interest accrued from the issue of principal at a rate of interest of 1312% and over time- period of 127 days by using the ordinary method can be done as shown below:
