Lying with a straight face...
Level
pending
One day, Mr and Mrs Tan asked their four children, Benedict, Bob, Brenda and Brian about whether they did their homework. They know that those who did are telling the truth while those who did not are lying.
Benedict: All four of us did our homework.
Bob : Three of us did our homework
Brenda : Two of us did our homework
Brian: One of us did our homework.
The one who is telling the truth is...
Benedict, Bob, Brenda or Brian?
