<h3>The interest rate is 8 % if your balance on an investment of 857 dollars at the end of six years is 1268.36 dollars</h3>
<em><u>Solution:</u></em>
Given that,
Principal = $ 857
Amount = $ 1268.36
Number of years = 6
Rate of interest = ?
Simple Interest = Amount - principal
Simple Interest = 1268.36 - 857
Simple Interest = 411.36
<em><u>Use the formula,</u></em>
![Simple Interest = \frac{ p \times n \times r}{100}\\\\411.36 = \frac{ 857 \times 6 \times r}{100}\\\\41136 = 5142 \times r\\\\r = \frac{41136}{5142}\\\\r = 8 \%](https://tex.z-dn.net/?f=Simple%20Interest%20%3D%20%5Cfrac%7B%20p%20%5Ctimes%20n%20%5Ctimes%20r%7D%7B100%7D%5C%5C%5C%5C411.36%20%3D%20%5Cfrac%7B%20857%20%5Ctimes%206%20%5Ctimes%20r%7D%7B100%7D%5C%5C%5C%5C41136%20%3D%205142%20%5Ctimes%20r%5C%5C%5C%5Cr%20%3D%20%5Cfrac%7B41136%7D%7B5142%7D%5C%5C%5C%5Cr%20%3D%208%20%5C%25)
