Find the simple interest and the total amount after three years.Principal = 7800 rupeesAnnual rate of interest = 9.5%Total interest=rupeesTotal amount =rupees

Answer 1

The value of the simple interest and the total value after three years is;

`\begin{gathered} \text{Total interest = 2223 rupees} \\ \text{Total amount = 10023 rupees} \end{gathered}`

Step-by-step explanation:

Given the following;

`\begin{gathered} \text{ Principal P= 7800 rupees} \\ \text{Annual rate of interest = 9.5\%} \end{gathered}`

We want to find the simple interest and the total amount after three years.

`t=3\text{ years}`

The simple interest formula;

`\begin{gathered} I=(Prt)/(100) \\ F=P+I \end{gathered}`

substituting the given values;

`\begin{gathered} I=(7800*9.5*3)/(100) \\ I=2223\text{ rupees} \end{gathered}`
`\begin{gathered} F=P+I=7800+2223 \\ F=10,023\text{ rupees} \end{gathered}`

Therefore, the value of the simple interest and the total value after three years is;

`\begin{gathered} \text{Total interest = 2223 rupees} \\ \text{Total amount = 10023 rupees} \end{gathered}`
