Question

at what rate of percents of money able itself in 10 years​

Answer 1

$\mathfrak{Answer:}$

= 10%.

$\mathfrak{Step-by-Step\;Explanation:}$

Let the principle be Rs. x.

So

• Simple interest = Rs. x.

Time = 10 years.

We know that ,

$\boxed{\bold{SI=\dfrac{Principle\times Time\times Rate}{100}}}\\\\\\\mathfrak{According\:to\:Question:}\\\\\\\implies\tt{x=\dfrac{x\times 10\times Rate}{100}}\\\\\\\implies\tt{Rate=\dfrac{100x}{10x}}\\\\\\\therefore\quad\tt{Rate=10\%.}\\\\\\\\\boxed{\boxed{\bold{Rate=10\%.}}}$

$\mathfrak{Extra\;info:}\\\\\\\textbf{If the interest is compounded annually then:}\\\\\\\bold{Amount=Principle\left(1+\dfrac{r}{100}\right)^n.}\\\\\\\tt{r=rate\quad\&\quad n=time.}$
