 \underline{ \underline{\bold{ \: \: GIVEN\: \: : \to}}} \\ \\ \bold{Amount \: ,\: A = Rs. \: 10360} \\ \\ \bold{Principal \:, \: P = Rs. \: 7000} \\ \\ \bold{Rate \: \: of \: \: interest \: ,\: R= \: 8\%} \\ \\ \\ \underline{\underline {\bold{ \: \: TO \: \: FIND\: \: : \to}}} \: \: \: \: \: \: \: \: \bold{Time \:, \: T= ?}

 \underline{ \underline{ \huge{ \mathbb{ \red{ \: \: IN \: \: SIMPLE \: \: INTEREST \: \: }}}}}

 \bold{Here,} \\ \\ \bold{Interest \: ,\: I = Amount \: - \: Principal} \\ \\ \bold{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = Rs. \: (10360 \: - \: 7000)} \\ \\ \bold{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = Rs. \: 3360}

 \underline{ \bold{ \: \: We \: \: know \: \: that\: \: }} \\ \\ \bold{I= \frac{P \times R \times T}{100} } \\ \\ \bold{ \Longrightarrow \: I \times 100 = P \times R \times T} \\ \\ \bold{ \Longrightarrow \: P \times R \times T = I \times 100} \\ \\ \bold{ \therefore \: \: } \: \: \boxed{\bold{T = \frac{ \: \: I \times 100 \: \: }{P \times R} }}

 \underline{ \bold{ \: \: Using \: \: this \: \: formula \: \: }} \\ \\ \\ \bold{ \therefore \: \: T = \frac{ \: \: 3360 \times 100 \: \: }{7000 \times 8} } \\ \\ \bold{ \: \: \: \: \: \: \: \: \: = \frac{336000}{56000} } \\ \\ \bold{ \: \: \: \: \: \: \: \: \: = 6}

 \bold{Hence,} \\ \\ \bold{ \underline{ \pink{ \: \: 6 \: \: years \: \: }} \: \: \: \: will \: \: it \: \: take \: \: for \: \: Rs. \: 7000} \\ \\ \bold{amount \: \: to \: \: Rs. \: 10360 \: \: at \: \: 8\% \: \: in} \\ \\ \bold{ \pink{ \: Simple\: \: Interest} \: .}
