B & G (Posted on 2013-06-03) Difficulty: 1 of 5
A boy and a girl are talking.
"I am a boy" - said the black child.
"I am a girl" - said the white child.
At least one of them lied.
Who is the boy and who is the girl?

The can't both be telling the truth - line 4.
line 1 states one boy and one girl.  If there were exactly one liar they would declare the same gender.
So there must be two liars. 

The girl is the one who claimed to be a boy and the boy is the one who claimed to be a girl.
