D Correct answer
Explanation

Let cost price = x. When sold at Rs. 116, profit = 116 - x. When sold at Rs. 92, profit = 92 - x. Given: profit at 116 is thrice profit at 92, so (116 - x) = 3(92 - x). Solving: 116 - x = 276 - 3x, which gives 2x = 160, so x = Rs. 80. Verification: Profit at 116 = 36, profit at 92 = 12, and indeed 36 = 3 × 12.
