If Meena gives an interest of ₹45 for one year at 9% rate p.a.. What is the sum she has borrowed?

Solution:

This question can be solved by using the formula of simple interest.

Simple Interest = [Principal × Rate × Time] / 100

Let us assume principal to be P

So, Simple Interest = [Principal × Rate × Time] / 100

The Simple interest, time and rate per annum is given as Rs. 45, 1 years and 9% respectively.

On substituting the values given in the question, we get

⇒ 45 = [P × 9 × 1] / 100

⇒ P = (45 × 100) / 9 × 1

⇒ P = 500

So, Meena borrowed Rs. 500.
