Question

simple interest on ₹ 1560 in 3 years is ₹ 585

Answer 1

Answer:

$Simple \:\: Interest = \dfrac{ PRT }{100}$

• P = Rs. 1560

• R = ?

• T = 3 years

• SI = Rs. 585

Substituting in the formula we get,

$\implies 585 = \dfrac{1560 \times R \times 3 }{100} \\ \\ \implies 585 \times 100 = 1560 \times 3 \times R\\\\\implies 58500 = 4680 \: R\\\\\implies R = \dfrac{ 58500}{4680} = 12.5 \: \%$

Hence the Rate of Interest is 12.5 %.

Answer 2

$\bold{ \mathbb{ \fbox{SOLUTION}}}$


Review Some Points:-


$\bold{ \mathbb{SIMPLE \: \: \: INTEREST= \frac{PRT}{100}}}$


$\bold{ \underline{here}}$

P(Principal)=1560

SI(Simple Interest)=585

(T)Time=3 years




$\mathbb{ \pink{ACCORDING \: \: TO \: \: THE \: \: FORMULA:-}}$


$\bold{585 \implies \frac{1560 \times 3 \times r}{100}} \\ \\ \\ \\ \\ 58500 \implies4680 \times r \\ \\ \\ \implies \frac{58500}{4680} = 12.5\%$


$\mathsf{conclusion - interest = 12.\%}$
