Found this in one of my old schoolbooks

1. E

2. His daughter

3. Which bag would the other gaurd give me? Take the other one

@Charmgoggles correct, you win a cookie 🍪

@Charmgoggles 2 could also be a priest.

@nik123 one two three... seven eight

@Charmgoggles But the lying policeman would say that the honest policeman would give you the sack of gold. If you take the other sack, you'll get the peanuts. Your answer is flawed.

@anto1ne97 No, here is the dialog:

Guy: "Hi lier, which bag would the other dude day has gold?"

(let's just say that the answer is the left one, but the lier will reverse it)

Lier: "The one on the right"

(then you take the other one (which is the one on the left)

@HTahboub @anto1ne97 the only flaw is that maybe the truth teller doesn't know that the other guy is a lier

@HTahboub That logic is sound.
Of course, being me, I made it way too complicated.

Other answer for 2: the man was lying
