Explanation

A = P(1 + r/100)^n. 5346.45 = P(1 + 0.09)^2 = P(1.09)^2 = P(1.1881). P = 5346.45 / 1.1881 = 4500.

AI explanation

Using the present value formula for compound interest, P = A / (1 + R/100)^n, we substitute the given values to find the principal. The calculation is 5346.45 / (1 + 9/100)^2, which simplifies to 5346.45 / (1.09 * 1.09). Dividing 5346.45 by 1.1881 gives the required investment of Rs. 4500.
