If you meant to ask what are the odds of answering a question right with four possible answers from a to d (25%,50%,60%,25%). If the correct answer is 25%, the actual percentage is 50%. if the correct answer is 50% or 60%, the actual percentage is 25%.
None of the answers are correct imo, probably around 33% would be my guess.
This is the key, it's random so it doesn't matter what the answers are therefore 25%.
felt good getting it right.
Anyhow, I thought of the problem the same way as Luke, and left out the retarded phrasing that the question was never brought up.

I see it as we don't know the question, we know one of the answers to be correct (A,B,C or D).
As A=D, the question is that what are the odds of picking a right answer out of 3 possible candidates (A,B or C). Obviously the odds are 1/3.
Yet again, it all depends how you want to understand the question.
