Answer 1

AnswEr :

$\bold{Given} \begin{cases} \sf{Principal=Rs. \: 3600} \\ \sf{Amount=Rs. \: 4320}\\ \sf{Rate=4\%\: p.a.} \\ \sf{Time=?}\end{cases}$

$\Longrightarrow \large \sf{Simple \: Interest = \dfrac{PRT}{100}}$

$\Longrightarrow \large \sf{(Amount - Principal)= \dfrac{PRT}{100}}$

$\Longrightarrow \large \sf{(4320 - 3600)= \dfrac{36 \cancel{00} \times 4 \times T}{ \cancel{100}}}$

$\Longrightarrow \large \sf{720= 36 \times 4\times T}$

$\Longrightarrow \large \sf{720= 144\times T}$

$\Longrightarrow \large \sf{ \cancel\dfrac{720}{144} = T}$

$\Longrightarrow \large \boxed{ \sf{T = 5 \: yrs.}}$
