Given :

  • Principal = Rs.400
  • Rate = 5 %
  • Time = 4 years

 \\ \\

To Find :

  • Simple Interest = ?

 \\ \qquad{\rule{200pt}{2pt}}

SolutioN :

 \maltese Formula Used :

  •  {\underline{\boxed{\pmb{\sf{ Simple \; Interest = \dfrac{ Principal \times Rate \times Time }{100} }}}}}

 \\ \\

 \maltese Calculating the Simple Interest :

 \begin{gathered} \qquad \; \dashrightarrow \; \sf { Simple \; Interest = \dfrac{ Principal \times Rate \times Time }{100} } \\ \\ \\ \\ \end{gathered}

 \begin{gathered} \qquad \; \dashrightarrow \; \sf { Simple \; Interest = \dfrac{ 400 \times 5 \times 4 }{100} } \\ \\ \\ \\ \end{gathered}

 \begin{gathered} \qquad \; \dashrightarrow \; \sf { Simple \; Interest = \dfrac{ 400 \times 20 }{100} } \\ \\ \\ \\ \end{gathered}

 \begin{gathered} \qquad \; \dashrightarrow \; \sf { Simple \; Interest = \dfrac{8000}{100} } \\ \\ \\ \\ \end{gathered}

 \begin{gathered} \qquad \; \dashrightarrow \; \sf { Simple \; Interest = \cancel\dfrac{8000}{100} } \\ \\ \\ \\ \end{gathered}

 \begin{gathered} \qquad \; \dashrightarrow \; {\pmb{\underline{\boxed{\purple{\sf{ Simple \; Interest = Rs. \; 80 }}}}}} \\ \\ \\ \\ \end{gathered}

 \\ \\

 \therefore \; Simple Interest on this sum of money is Rs.80 .

According to question

✠ Given that:-

  • Principal = ₹400
  • Time = 4 years
  • Rate = 5%

✠ To find:-

  • Simple interest per annum.

✠ Formula used:-

\large\boxed{\sf{ \red { \implies \frac{P\times R\times T}{100} = SI }}}

Where,

  • P=Principal
  • R=Rate
  • T=Time
  • SI=Simple interest

Solution:-

\large{\sf{ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   \implies\frac{P×R×T}{100} }}

\large{\sf{  \:   \:  \: \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \implies\frac{400 \times 4 \times 5}{100} }}

\large{\sf{ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   \implies4 \times 4 \times 5}}

\large{\sf{ \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \:  \:  \:  \implies ₹80 }}

\large{\sf{  \maltese\star\:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \boxed{ \implies SI=₹8}}}

Hence, The simple interest would be 80 if the

  • Principal=400
  • Rate=5%
  • Time=5 years
