C Correct answer
Explanation

Let CP be cost price. Profit at Rs. 3460 equals twice the profit at Rs. 3280: (3460 - CP) = 2(3280 - CP). Solving: 3460 - CP = 6560 - 2CP, giving CP = 3100. At this CP, selling at Rs. 3460 gives profit of Rs. 360, and selling at Rs. 3280 gives profit of Rs. 180 - exactly double the relationship stated.
