Under the assumption that at least one of those answers is “correct” and fixed (not changing with respect to guesses) and that all options are listed, it is either 25 or 50 percent. 25 if the “correct” answer is either 50 or 60 (or exactly one of the 25’s), and 50 if the correct answer is 25.
Clearly this requires a departure from the expected definitions of the words and/or numbers in the question. It’s terrible question writing, I’ll say.
I’d argue it’s 50% by process of eliminating with some grouping. 60% is right out, as it doesn’t make sense. This essentially leaves us with 50% and 25%, and since there’s 2 options a random guess would have a 50% chance of being correct
