The rate of interest is 25%
<u>Explanation:</u>
Given:
Principal, P = $2,000
Amount, A = $2500
Time, t = 1 year
Rate of Interest, r = ?
We know:
![Amount = P(1+\frac{r}{100})^t](https://tex.z-dn.net/?f=Amount%20%3D%20P%281%2B%5Cfrac%7Br%7D%7B100%7D%29%5Et)
On substituting the value we get:
![2500 = 2000 (1 + \frac{r}{100})^1\\ \\\frac{25}{20}= (1+\frac{r}{100})\\](https://tex.z-dn.net/?f=2500%20%3D%202000%20%281%20%2B%20%5Cfrac%7Br%7D%7B100%7D%29%5E1%5C%5C%20%5C%5C%5Cfrac%7B25%7D%7B20%7D%3D%20%281%2B%5Cfrac%7Br%7D%7B100%7D%29%5C%5C)
![\frac{5}{20} = \frac{r}{100}\\ \\r = \frac{100 X 5}{20} \\\\r = 25](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B20%7D%20%3D%20%5Cfrac%7Br%7D%7B100%7D%5C%5C%20%20%5C%5Cr%20%3D%20%5Cfrac%7B100%20X%205%7D%7B20%7D%20%5C%5C%5C%5Cr%20%3D%2025)
Therefore, the rate of interest is 25%
