Answer 1

The sum borrowed is Rs.500.

Step-by-step explanation:

Given : If Meena gives an interest of Rs.45 for one year at 9% rate p.a.

To find : What is the sum she has borrowed ?

Solution :

Applying interest formula,

I= P*T*R

Where, I=Rs.45 is the interest

R=9%=0.09 is the interest rate

T=1 year is the time

P is the principal or sum

Substitute the value in the formula,

45 = p*0.09*1

P= 45/0.09

P= 500

Therefore, The sum borrowed is Rs :500

Answer 2

₹500

given: S.I=Rs.45

R=9%, T=1 year

$S.I= \frac{P \times T \times R}{100} = 45= \frac{ {P \times 1 \times 9}}{100}$

The sum she has borrowed P=₹500
