D Correct answer
Explanation

Let CP be x. 4080 - x = x - 3650. 2x = 7730. x = 3865.

AI explanation

Let the cost price be x and the equal profit and loss amount be y. When sold for Rs. 4,080, the equation is x + y = 4080. When sold at a loss for Rs. 3,650, the equation is x - y = 3650. Adding both equations gives 2x = 7730, so x = 3865. The cost price of the wrist watch is Rs. 3,865.
