A Correct answer
Explanation

Amount = P * (1 + r/100)^n. 6336 = P * (1 + 20/100)^2 = P * (1.2)^2 = P * 1.44. P = 6336 / 1.44 = 4400.

AI explanation

Using the compound interest formula A = P(1 + R/100)^T, substitute the given values to find the principal. The equation becomes 6336 = P(1 + 20/100)^2, which simplifies to 6336 = P(1.2)^2. This further reduces to 6336 = 1.44P, so dividing 6336 by 1.44 gives P = Rs. 4400.
