My next door neighbour lies a lot. In fact, he only tells the truth on one day a week! One day he told me, “I lie on Mondays and on Tuesdays.”The next day he said, “Today is either Thursday, Saturday or Sunday.”The next day he said, “I lie on Wednesdays and Fridays.”
On which day of the week does my neighbour tell the truth?

- One of the statements "I lie on Monday and Tuesday" and "I lie on Wednesday and Friday" is false and one is true.
So he either tells the truth on Monday/Tuesday/Wednesday/Friday. We can also conclude that he surely lies on the second day.
Lets call the days mentioned as Day 1, Day 2 and Day 3.
Case 1: Truth on Monday
==> (Day 1= Saturday Day 2= Sunday Day 3=Monday)
Wrong (Day 2 !=Thursday/Saturday/Sunday as he lies on second day)
Case 2: Truth on Tuesday
==> (Day 1= Sunday Day 2= Monday Day 3=Tuesday)
Possible (Day 2 !=Thursday/Saturday/Sunday as he lies on second day)
Case 3: Truth on Wednesday
==> (Day 1= Wednesday Day 2= Thursday Day 3=Friday)
Wrong ( Day 2 !=Thursday/Saturday/Sunday as he lies on second day )
Case 4: Truth on Friday
==> (Day 1= Friday Day 2= Saturday Day 3=Sunday)
Wrong ( Day 2 !=Thursday/Saturday/Sunday as he lies on second day )
So the man speaks the Truth on Tuesday - 9 years agoHelpfull: Yes(6) No(1)
