Question

Find the rate on principal =8250 si=1100 time =2years

Answer 1

Answer:

Rate = 26.66 %

Step-by-step explanation:

Principal = ₹8250

Time = 2 years

Simple Interest = ₹1100

Rate = ?

Simple Interest = $\frac{Principal * Rate * Time}{100}$

Rate = $\frac{Simple Interest * 100}{Principal * Time}$

        = $\frac{1100 * 100}{8250 * 2}$

        = 26.66 %

$\green{ \underline \bold{Given : }} \\ : \implies \text{Principal(p)= 8,250\:rupees} \\ \\ : \implies \text{Simple \: interest(S.I) = 1100\:rupees} \\ \\ : \implies \text{Time(t) = 2\:years} \\ \\ \red{ \underline \bold{To \: Find: }} \\ : \implies \text{Rate(r) = ?}$

• According to given question :

$\bold{As \: we \: know \: that } \\ \circ \: \text{Simple \: interest} = \frac{ \text{Principal }\times \text{ Rate} \times \text{Time}}{100} \\ \\ \bold{Putting \: given \: values} \\ : \implies S.I = \frac{p \times r \times t}{100} \\ \\ : \implies 1100= \frac{8250\times r\times 2 }{100} \\ \\ : \implies r= \frac{ 1100\times 100}{8250 \times 2 } \\ \\ \green{ : \implies \text{r = 6.66\%}} \\ \\ \green{ \therefore \text{Rate=6.66\%}} \\ \\ \bold{Basic \: formula\:related\:to\:C.I} \\ \circ \: A = p(1 + \frac{r}{100} )^{t}$
