B Correct answer
Explanation

Amount = P + SI = P + (P * R * T) / 100. 8100 = P + (P * 7 * 5) / 100 = P + 0.35P = 1.35P. P = 8100 / 1.35 = 6000.

AI explanation

Let the principal be P, so the amount is P + (P * 7 * 5) / 100 = 8100. This simplifies to P + 0.35P = 8100, or 1.35P = 8100. Solving for P gives 8100 / 1.35 = 6000, so the amount borrowed was Rs. 6000.
