has borrowed?​

Answer 1

Answer:

Principal = ₹500

Step-by-step explanation:

Let the Principal = p

rate = 9%p.a.

time = 1year

Simple Intrest = ₹45

p = si×100/r×t

= 45×100/9×1

= 5×100

= 500

Answer 2

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.
