### Intel Logic Aptitude Interview Question

Intel Logic Aptitude Interview Question - 18 March

Three brothers are identical triplets.
-: The oldest(my minutes) is Sanjay and he is so honest that he always tells the truth.
-: The next oldest is Anurag and he always lies.
-: The next and the youngest is Anmol and he sometimes lies and sometimes tells the truth.

Aditi, an old friend of the the brothers visited them after a long time and did not recognize them.
:- Aditi asked the brother that was sitting on the left, 'Which brother is in the middle of you three?' and the answer she received was, 'Oh, that's Sanjay.'
:- Aditi then asked the brother in the middle, 'What is your name?' The response given was, 'I am Anmol'
:- Aditi turned to the brother on the right, then asked, 'Who is that in the middle?' The brother then replied, 'He is Anurag.'

2. Anmol is on the left, Anurag in the middle, and Sanjay on the right.

Explanation: When Aditi inquires the brother on the left as to who is sitting in the middle, he replies Sanjay, Now this brother on the left can't be Sanjay, since that would mean he would be lying about the brother in the middle; and Sanjay never lies. This means the person on the left is either Anurag, who always lies, or Anmol, who may or may not lie. Also, Sanjay can't be the middle brother; since the latter tells Aditi he is Anmol(remember, Sanjay never lies!). So, Sanjay is sitting on the right. When Aditi inquires the brother on the right(whom we have proved to be Sanjay) as to who is in the middle, he says Anurag. He is right, since Sanjay never spoke false. This would then leave Anmol to be on the far left.

3. Anurag the liar , lied
