B: No, today is Wednesday.
C: Both of you are wrong, Wednesday is tomorrow.
D: Today is neither Monday, nor Tuesday, nor Wednesday.
E: I am pretty sure that Thursday was yesterday.
F: No, yesterday was Tuesday.
G: All I know, is yesterday wasn’t Saturday.
Only one of them is telling the truth.
On which day did the argument take place?
Answer: They argued on a Sunday.
The table below summarizes the event.
A cross (x) indicate the possible days if that person’s statement is true.
The only column with a single ‘x’ is on Sunday, therefore D is the only person who is correct.
