Question

If meena gives an interest of ₹45 for 1year at 9%p.a ❤what is the sum she borrowerd? plz help plz plz​

Answer 1

Answer:

₹500

Step-by-step explanation:

Simple Interest (S.I. )

$= \frac{p \times r \times t}{100 }$

where P = principal

R = rate

and T = Time.

Here ,

Simple Interest (SI) = ₹45

Principal(P) =?

Rate (R)= 9%

Time(T) = 1 year.

Then ,

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

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

$p = \frac{4500}{9} \\ = 500$

P = ₹500.
