Question 1186683
.
a loan of 2700$ can be repaid in 100 days by paying the principal sum borrowed 
plus 75$ interest what was the rate if interest charged
~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
This problem is on simple interest

    75 = {{{2700*r*(100/365)}}},


where r is the simple interest per year (365 days).

From this equation, we find

    r = {{{(75*365)/(2700*100)}}} = 0.101388889


or 0.1 = 10% per year approximately.    <U>ANSWER</U>
