A Correct answer
Explanation

CP1 = 990 / 1.1 = 900. CP2 = 990 / 0.9 = 1100. Total CP = 900 + 1100 = 2000.

AI explanation

Using the cost price formula for equal selling prices and equal profit and loss percentages, Total Cost Price = (2 * Selling Price * 100) / (100 + Profit% - Loss%). Substituting the given values into the formula gives (2 * 990 * 100) / (100 + 10 - 10) = 198000 / 100, resulting in a total cost price of Rs. 2000.
