Today’s expression is “Your guess is as good as mine.” This very common phrase lets you say that you don’t know or understand something, but in a more native-sounding way.
Imagine looking at a complex math problem on a board with a friend. Neither of you enjoys math, and has no idea about how to solve the equation.
When your friend asks you what you think the answer is, you can only guess. So by telling him that “Your guess is as good as mine,” you’re saying that you don’t know, and any answer you might say has the same chance of being correct as anything else.
“Your guess is as good as mine” is a phrase you can use in both professional and casual situations:

A: Do you know how to put this bookcase together? I just got it and it has no instructions.
B: No idea. Your guess is as good as mine.

A: Your guess is as good as mine, so what do you think we should do about the problem at work?
B: I wish I knew. Let’s ask Bob. He always knows what to do.

A: Ted’s opinion is as good as mine, so ask someone more knowledgeable.
B: Sounds good. Better to be safe than sorry.

A: Maybe we shouldn’t eat this. Can you tell what’s in it?
B: Your guess is as good as mine.
