A Correct answer
Explanation

This is a compound interest problem where we solve for the principal (P). Using A = P(1 + r)^t, where A = 5467.5, r = 12.5% = 0.125, t = 3 years. Then P = A / (1.125)^3 = 5467.5 / 1.4238 ≈ 3840. The calculation (1.125)^3 = 1.423828125, and 5467.5 / 1.423828125 = 3840 exactly. Option A (Rs. 3840) is correct.
