Answer 1

Here Is Your Answer  :-

Principal :- ₹56000

Time :- 2 years

S.I. :- ₹280

Rate  =  (S.I. x 100)/(P x R)

         =  (₹280 x 100)/(₹56000 x 2)

         =  1/4 %

Answer 2

GIVEN :-

• Principal (P) = Rs.56000
• Simple Interest (S.I) = Rs. 280
• Time (T) = 2 years.

TO FIND :-

• The rate of interest (R)

SOLUTION :-

$\boxed { \bf \: \implies R \: = \dfrac{ S.I \times 100}{ P \times T } }$

$\implies \tt \: R \: = \frac{280 \times 100}{56000 \times 2} \\ \\ \implies \tt \: R \: = \frac{28000}{112000} \\ \\ \implies \tt R \: = \frac{28}{112} \\ \\ \implies \tt \: \:R = 0.25 \% \: \: p.a$

Hence Rate of Interest (R) = 0.25 %. p.a

ADDITIONAL INFORMATION :-

$\boxed{\begin{minipage}{6cm} \\ \bf{ \underline{Some Formulae}} \\ \\ \rightarrow \quad \sf P = \dfrac{100 \times S.I}{R \times T} \\ \\ \\ \rightarrow \quad T = \dfrac{100 \times S.I}{P \times R} \\ \\ \\ \rightarrow \quad R = \dfrac{100 \times S.I}{P \times T} \\ \\ \\ \rightarrow \quad A = P + S.I \\ \\ \\ \rightarrow \quad S.I = \dfrac{P \times R \times T}{100} \\ \end{minipage}}$
