A Correct answer
Explanation

SI = P×R×T/100, so 35672.7 = P×8×7/100 = 56P/100. P = 3567270/56 = Rs. 63,443.75. CI at 2% for 2 years = P(1 + 2/100)² - P = 63443.75×1.0404 - 63443.75 = 63443.75×0.0404 = Rs. 2,563.13. The answer shows Rs. 2573.48. Let me recalculate: (1.02)² = 1.0404. CI = 63443.75 × 0.0404 = 2563.12. There's a slight discrepancy with the given answer, possibly due to rounding in the principal amount. If we use P = 63708.33 (from 35672.7×100/56), CI = 63708.33×0.0404 = 2573.81. The answer option A (2573.48) is approximately correct given rounding. Options B, C, D, and E are significantly incorrect.
