Question

If Rishabh deposited Rs.150000 in a bank for 3 years at the rate of 8 p.c.p.a. How much amount will he receive at the end of the period? ​

Answer 1

$\bf \: \underline { Given }\: :$ ↴

$\sf \: Principal \: : \: Rs. \: 150000$

$\sf \: Rate \: of \: Interest : 8 \: \%$

$\sf \: Time \: : \: 3 \: Years.$

$\bf \: \underline{To \: find }\: :$ ↴

$\sf \: Total \: amount \: he \: receives \: at \: end \: of \: the \: period.$

$\bf \: \underline{Formula \: used} :$ ↴

$\sf \large \star \ \tt\purple{\boxed{\sf \: Amount \: = \:Simple \: Interest + Principal}} \: \star$

$\bf \: \star \: \underline{So, \: Let's \: Start }\: \star$

$\sf \: Simple \: Interest \: :-$

$\sf \: \longrightarrow \: \dfrac{Principal \times Rate \times Time }{100}$

$\sf \longrightarrow \: \dfrac{150000 \times8 \times 3}{100}$

$\longrightarrow \: \dfrac{1500 \times 8 \times 3}{1}$

$\tt \longrightarrow \: 1500 \times 24 = \boxed{\tt 36000}$

$\sf \: Total \:Amount \:will \:be \: :-$

$\sf \: {\sf \longrightarrow \: 36000 + 150000}$

${\sf \: \longrightarrow \: \boxed{\sf \: Rs. \: \: 186000}}$

$\blue{ \sf \: The \: total \: amount \: that \: Rishabh\: will \: receive \: is \: Rs. \: 186000}$

$\sf \: \underline{ Some \: related \: formulas} \: :-$

${\sf \to \boxed{\sf Principle = \dfrac{SI \times 100}{R \times T}}}$

${\sf \to \boxed{\sf Simple \: Interest = \dfrac{P \times R \times T}{100}}}$

${\sf \to \boxed{ \sf Rate \: of \: Interest = \dfrac{SI \times 100}{P \times T}}}$

${\sf \to \boxed{\sf Time = \dfrac{SI \times 100}{P \times R}}}$
