Today's Question - A boy and a girl are talking. "I'm a boy" says the one with dark hair. "I'm a girl" says the one with blonde hair. If at least one of them is lying, which is which and what color is the girl's hair?

Reveal Answer Answer \xe2\x80\x93 To solve you had to deconstruct the question. We were told at least one was lying. So if only one lied and the other told the truth, the gender claims should have been the same (e.g. Boy lies and says he\xe2\x80\x99s a \xe2\x80\x9cgirl\xe2\x80\x9d. Truthful girl must say she\xe2\x80\x99s a \xe2\x80\x9cgirl\xe2\x80\x9d.) So, since we got claims of boy/girl they both must be lying. Therefore the girl had dark hair.
