A Correct answer
Explanation

Let CP of A be x. B buys at 1.05x. C buys at 1.1 * 1.05x = 1.155x. 1.155x = 2310. x = 2310 / 1.155 = 2000.

AI explanation

Using the successive selling price formula, the final price equals the original cost price multiplied by 1.05 and then by 1.10. So, 2310 = x times 1.155. Dividing 2310 by 1.155 gives the original cost price of 2000.
