Question

john deposit rs 1500 in a bank. the bank pays 8% per annum. find the interest and amount to be received by him after 3 yrs

Answer 1

Given :

• Principal = Rs.1500
• Rate = 8 %
• Time = 3 years

To Find :

• Simple Interest = ?
• Amount = ?

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

SolutioN :

$\maltese$ Formula Used :

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

• ${\underline{\boxed{\pmb{\sf{ Amount = Principal + Simple \; Interest }}}}}$

$\maltese$ Calculating the Interest :

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

$\begin{gathered} \qquad \; \longmapsto \; \; \sf { Simple \; Interest = \dfrac{1500 \times 8 \times 3}{100} } \\ \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; \longmapsto \; \; \sf { Simple \; Interest = \dfrac{12000 \times 3}{100} } \\ \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; \longmapsto \; \; \sf { Simple \; Interest = \dfrac{36000}{100} } \\ \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; \longmapsto \; \; \sf { Simple \; Interest = \cancel\dfrac{36000}{100} } \\ \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; \longmapsto \; \; {\underline{\boxed{\pmb{\sf{ Simple \; Interest = Rs. \; 360 }}}}} \; {\orange{\pmb{\bigstar}}} \\ \\ \\ \end{gathered}$

$\maltese$ Calculating the Amount :

$\begin{gathered} \qquad \; \dashrightarrow \; \; \sf { Amount = Simple \; Interest + Principal } \\ \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; \dashrightarrow \; \; \sf { Amount = 360 + 1500 } \\ \\ \\ \end{gathered}$

$\begin{gathered} \qquad \; \dashrightarrow \; \; {\underline{\boxed{\pmb{\sf{ Amount = Rs. \; 1860 }}}}} \; {\purple{\pmb{\bigstar}}} \\ \\ \\ \end{gathered}$

$\therefore \;$ Interest is Rs.360 and the Amount is Rs.1860 .

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