To Find : Find the 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 Interest :

$\begin{gathered} \qquad \; \; \longrightarrow \; \; \sf { S.I = \dfrac{ Principal \times Rate \times Time }{ 100 } } \\ \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; \; \longrightarrow \; \; \sf { S.I = \dfrac{ 350 \times 5 \times 2 }{ 100 } } \\ \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; \; \longrightarrow \; \; \sf { S.I = \dfrac{ 350 \times 10 }{ 100 } } \\ \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; \; \longrightarrow \; \; \sf { S.I = \dfrac{ 3500 }{ 100 } } \\ \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; \; \longrightarrow \; \; \sf { S.I = \cancel\dfrac{ 3500 }{ 100 } } \\ \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; \; \longrightarrow \; \; {\underline{\boxed{\pmb{\sf{ Simple \; Interest = Rs. \; 35 }}}}} \; {\purple{\bigstar}} \\ \\ \\ \end{gathered}$

$\therefore \;$ Simple Interest on this sum of money is Rs.35 .
