what will principle and simple interest ​

Answer 1

Answer:

principal=535 rate=3.5% time=2years

ans. 37.45

Answer 2

GIVEN:-

• Rate of interest (R) = 3.5%
• Time (T) = 2 years
• Amount (A) = ₹ 535

TO FIND:-

• Principle (P)
• Simple Interest (SI)

SOLUTION:-

$☯\underline{\boldsymbol \red{According\: to \:the \: Formula:}}$

$\huge \green \bigstar \huge \boxed{\sf{SI= \frac{P \: \times R×T}{100} }}$

$\huge \therefore \large\sf{SI = \dfrac{(A - SI) \times 3.5 \times 2}{100} }$

$: \large\implies \sf{SI = \dfrac{(535 -SI) \times 3.5 \times 2}{100} }$

$: \large \implies \sf{SI = \dfrac{7(535 - SI)}{100}}$

$: \large \implies \sf{SI = \dfrac{3745 - 7SI}{100} }$

$: \large\implies \sf{100SI = 3745 - 7SI}$

$: \large\implies \sf{100SI +7SI = 3745 }$

$: \large\implies \sf{107SI = 3745}$

$: \large \implies \sf{SI = \cancel\dfrac{3745}{107}}$

$: \large \implies \sf \pink{SI =₹ \: 35}$

☯$\begin{gathered}\underline\red{\boldsymbol{According\: to \:the\:Formula:}} \\\end{gathered}$

$\huge \green\bigstar \huge \boxed{ \sf{P = A - SI}}$

$\huge \therefore \large \sf{P = 535 - 35}$

$: \large \implies \sf \pink{P = ₹ \: 500 }$

ANSWERS:-

• Simple Interest = ₹ 35
• Principal = ₹ 500
