Given :-
The Simple Interest (S.I) = Rs 45
The Time (T) = 4 years
Rate of Interest (R) = 9% per annum
To be found :-
The Principal (P)
We can find,
Principal (P) using the Simple Interest (S.I) formula and
we have Simple interest (S.I), Time (T), and Rate of Interest (R)
So,
⇒ 45 =
⇒ 45 × 100 = [transporting 100 to LHS]
⇒ 4500 ÷ 36 = P [transporting 36 to LHS]
⇒ 125 = P
∴ Principal (P) = Rs 125
Hence,
The sum of of money or the Principal which was borrowed = Rs 125
Verified answer
Answer:
Step-by-step explanation:

45=Px9x4/100
45=Px9x1/25
P=45x25/9
=5x25
=125
Therefore, the sum she has borrowed is 125 rupees
