Explanation

Simple Interest formula: SI = P × R × T / 100. Given SI = Rs. 8160, R = 15%, T = 4.25 years. So 8160 = P × 15 × 4.25 / 100 = P × 63.75 / 100 = P × 0.6375. Therefore P = 8160 / 0.6375 = Rs. 12800. The calculation is straightforward once you set up the SI formula correctly. Option B matches this result.
