Question

If Meena gives an interest of Rs 45 for one year at $9\%$ rate p.a, what is the sum she has borrowed?

Answer 1

Here,
Given that
Meena pays an interest of Rs 45 for one year.
The rate of interest is $9\%$

Interest = Rs 45

Time = 1 year

Rate of interest = $9\%$

Principal =?

We know that,

$S.I=\frac{P\times R\times T}{100}$

$45=\frac{P\times 9\times 1}{100}$

$\Rightarrow P=\frac{45\times 100}{9}$

$\therefore P=Rs.500$

The sum she borrowed is Rs 500.
