Three sisters are identical triplets.
=> The oldest(in minutes) is aishwarya and she always speaks the truth
=> Next to aishwarya is kareena and she always lies.
=> The youngest of three sister is katrina and she sometimes lies and sometimes tells the truth.
Salman, an old friend of the sisters visited them after a long time and did not recognize them.
=> Salman asked the sister that was sitting on the left, 'Which sister is in the middle of you three?' and the answer she received was, 'Oh, that's aishwarya.'
=> Salman then asked the sister in the middle, 'What is your name?' The response given was, 'I am katrina'
=> Salman turned to the sister on the right, then asked, 'Who is that in the middle?' The sister then replied, 'He is kareena.'
Salman got confused.
She had asked the same question three times and received three different answers.
Who was who ?
