Given:
Principal = Rs. 6000
Rate of simple interest = 6% per annum.
Time = 4 years
To find:
The simple interest and amount.
Solution:
Formula for simple interest:
![I=(P* r* t)/(100)](https://img.qammunity.org/2022/formulas/mathematics/high-school/40w6wkssmvbfxlmeqqyvlr567scysa97rc.png)
Where, P is principal, r is the rate of interest and t is the number of years.
Putting P=6000, r=6 and t=4, we get
![I=(6000* 6* 4)/(100)](https://img.qammunity.org/2022/formulas/mathematics/high-school/6n6jez2w1qw7ru5ymxel5yhwlpy3tyzwe3.png)
![I=60* 6* 4](https://img.qammunity.org/2022/formulas/mathematics/high-school/gzm1ygnxgllsceodxr8fy2ooe2w6urlz3a.png)
![I=1440](https://img.qammunity.org/2022/formulas/mathematics/high-school/monxc5vallzyqwrxkhyxwgzj5oube9eoy6.png)
Now,
![Amount=Principal+Interest](https://img.qammunity.org/2022/formulas/mathematics/high-school/g4o1x23z799fwvgqbdelqnbi9uichxw558.png)
![Amount=6000+1440](https://img.qammunity.org/2022/formulas/mathematics/high-school/shepsotpplsyuc1ewtpjom4gtjrgrphpkm.png)
![Amount=7440](https://img.qammunity.org/2022/formulas/mathematics/high-school/50ycmlupi2pxdgv4zgsw93aqa6mfreiqzr.png)
Therefore, the simple interest is Rs. 7440 and the amount is Rs 7440.
