Question

Find the principal of time =3years , si= 600 rupees ,rate = 4℅

Answer 1

Step-by-step explanation:

so the principal is RS 5000

Answer 2

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

$\green{\therefore{\text{Principal=5,000\:rupees}}}$

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

$\green{ \underline \bold{Given : }} \\ : \implies \text{Time (t)= 3 \: years} \\ \\ : \implies \text{Simple \: interest(S.I) = 600} \\ \\ : \implies \text{Rate(r) = 4\%} \\ \\ \red{ \underline \bold{To \: Find: }} \\ : \implies \text{Principal(p) = ?}$

• According to given question :

$\bold{As \: we \: know \: that } \\ \circ \: \text{Simple \: interest} = \frac{ \text{Principal }\times \text{ Rate} \times \text{Time}}{100} \\ \\ \bold{Putting \: given \: values} \\ : \implies S.I = \frac{p \times r \times t}{100} \\ \\ : \implies 600 = \frac{p \times 4 \times3 }{100} \\ \\ : \implies p = \frac{600 \times 100}{3 \times4 } \\ \\ \green{ : \implies \text{p = 5000 \: rupees}} \\ \\ \green{ \therefore \text{principal = 5000 \: rupees}} \\ \\ \bold{Basic \: formula\:related\:to\:C.I} \\ \circ \: a = p(1 + \frac{r}{100} )^{t}$
