There are three identical triplets sisters. Demi is the oldest of them all and she always speaks the truth. Diana is the next one who is a liar always. Drew, the youngest of them all speaks both truth and lies randomly.
On a rainy day, a family friend Victor visited them. Since there were starkly identical, he was not able to recognize them. Thus to clarify, he asked one question to each one of them.
He started with the one standing on the left and asked, 'Which sister is in the middle of you three?' She answered, 'That's Demi.'
Then, he asked the one standing in the middle, 'What is your name?' She answered, 'I am Drew.'
Finally, he asked the one standing on the right, 'Who is standing in the middle?' She answered, 'She is Diana.'
Victor was left baffled. He asked the questions three times and received different answers every time.
