Textbook Problem

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
9. $32,400 8.6 241 ______________ ________________

To determine

To calculate: The comparison between exact interest and the ordinary interest for the loan of $32400 over a period of 241days at a rate of interest of 8.6% per annum by Exact interest method and ordinary interest method.

Explanation

Given Information:

The loan of $32400 is taken at the rate of interest, 8.6% per annum for the time period of 241 days.

Formula used:

The simple interest formula is:

I=P×R×T

Where, T is the time period in years, P is principal value and R is rate.

For exact interest, T=Number of days of loan365

For ordinary interest, T=Number of days of loan360

Calculation:

Consider the data provided as the loan of $32400 is taken at the rate of interest of 8.6% per annum for the time period of 241 days.

Then the Interest can be calculated in the following manner,

The time period for exact interest is,

T=241365 year.

Assume, P=$32400, R=8.6% and T=241365

As, the formula for simple interest:

I=P×R×T

To find the value of interest, substitute P=$32400, 8
