$\bf Question$

The simple interest on ₹ 800 invested for 13% per annum for 3 years is ___.

$\bf To \: Find$

We have to find simple interest

Answer:

The simple interest is ₹312

Step-by-step explanation:

Simple interest on ₹ 800 means Principal is ₹ 800 and Rate is 13% time period is 3 years

We have to find simple interest

$\bf \: Formula \: used$

$\: \: \: \: \: \: \: \underline{ \boxed{ \rm S.I = \dfrac{P \times R \times T}{100} }}$

Where,

S.I = Simple interest

P = Principal

R = Rate

T = Time

Now,

P = Rs. 800

R = 10%

T = 3

Now, put values in formula

$\begin{gathered} \implies \bf S.I = \dfrac{P \times R \times T}{100} \\ \\ \end{gathered}$

$\begin{gathered} \implies\bf S.I = \dfrac{800 \times 13 \times 3}{100} \\ \\ \end{gathered}$

$\begin{gathered}\implies\bf S.I = \dfrac{8 \cancel{ 00} \times 13 \times 3}{1 \cancel{00}} \\ \\ \end{gathered}$

$\begin{gathered}\implies\bf S.I =8 \times 13 \times 3 \\ \\ \end{gathered}$

$\begin{gathered}\implies\bf S.I =8 \times 13 = 104 \\ \\ \end{gathered}$

$\implies\bf S.I = 104 \times 3$

$\implies\bf S.I = ₹ \: 312$

Required Answer :-

The simple interest is ₹312.
