Question

principal is = 5000 rate = 9% p.a and time is =
146 days find the simple interest and amount

Answer 1

I=5000*3*146/365*100
I=180
so a = 5000+180=518.

Answer 2

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

$\green{\therefore{\text{Simple\:interest=180\:rupees}}}$

$\green{\therefore{\text{Amount=5180\:rupees}}}$

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

$\green{ \underline \bold{Given : }} \\ : \implies \text{Time (t)= 146 \:days} \\ \\ : \implies \text{Principal(p) = 5000\:rupees} \\ \\ : \implies \text{Rate(r) = 9\%} \\ \\ \red{ \underline \bold{To \: Find: }} \\ : \implies \text{Simple\:interest(S.I) = ?}\\\\ :\implies \text{Amount(A)=?}$

• According to given question :

$\bold{As \: we \: know \: that } \\ \circ \: \text{Simple \: interest} = \frac{ \text{Principal }\times \text{ Rate} \times \text{Time}}{100} \\ \\ \bold{Putting \: given \: values} \\ : \implies S.I = \frac{p \times r \times t}{100} \\ \\ : \implies S.I = \frac{5000\times 9 \times\frac{146}{365} }{100} \\ \\ : \implies S.I = \frac{5000\times 9\times 146}{ 100\times 365 } \\ \\ \green{ : \implies \text{S.I= 180\: rupees}} \\ \\ \green{ \therefore \text{Simple\:interest = 180 \: rupees}} \\ \\ :\implies \text{Amount=S.I+Principal}\\\\ \green{:\implies \text{Amount=180+5000=5180\:ruppes}}\\ \\ \bold{Basic \: formula\:related\:to\:CI} \\ \circ \: A = p(1 + \frac{r}{100} )^{t}$
