Answer 1

please comment me it is wrong or right

Answer 2

$\blue{\bold{\underline{\underline{Answer:}}}}$

$\green{\therefore{\text{Time=3.72\:years}}}$

$\orange{\bold{\underline{\underline{Step-by-step\:explanation:}}}}$

$\green{ \underline \bold{Given : }} \\ : \implies \text{Principal(p)= 6400\:rupees} \\ \\ : \implies \text{Simple \: interest(S.I) = 1908\:rupees} \\ \\ : \implies \text{Rate(r) = 8\%} \\ \\ \red{ \underline \bold{To \: Find: }} \\ : \implies \text{Time(t) = ?}$

• According to given question :

$\bold{As \: we \: know \: that } \\ \circ \: \text{Simple \: interest} = \frac{ \text{Principal }\times \text{ Rate} \times \text{Time}}{100} \\ \\ \bold{Putting \: given \: values} \\ : \implies S.I = \frac{p \times r \times t}{100} \\ \\ : \implies 1908= \frac{6400 \times 8\times t }{100} \\ \\ : \implies t = \frac{ 1908\times 100}{6400 \times 8 } \\ \\ \green{ : \implies \text{t = 3.72\: years}} \\ \\ \green{ \therefore \text{Time = 3.72\: years}} \\ \\ \bold{some \: basic \: formula} \\ \circ \: A = p(1 + \frac{r}{100} )^{t}$
