Explanation

A's investment: 5600 for year 1, then 5600 × 1.25 = 7000 for year 2. Investment-time product = 5600 + 7000 = 12600. B's: 6300 for year 1, then 6300 × 1.10 = 6930 for year 2. Product = 6300 + 6930 = 13230. Ratio A:B = 12600:13230 = 20:21. A's profit = 3690 × 20/41 ≈ Rs. 1800. Since this exact value isn't among the given options (1600, 1720, 1890, 1900), the correct choice is 'None of these'.
