7 friends - Amar, Bablu, Chintu, Dawood, Emraan, Farza and Gautam - are sitting in a straight line facing North. Further:
1) Dawood and Bablu are sitting beside each other.
2) Amar and Emraan have two people in between them.
3) Dawood is not an immediate neighbour of either Chintu or Gautam.
4) Neither Chintu nor Gautam sits at the extreme ends.
5) Third to the left of Gautam sits Chintu.
6) Exactly one person sits between Emraan and Chintu.
Third to the left of Gautam sits Chintu and neither of them sit at the extremes => Gautam can sit either on the fifth place or the sixth place.
If Gautam sits in the sixth place, then Chintu sits in the third place.
Exactly one person sits between Emraan and Chintu => Emraan can sit in either the first place or the fifth place. Either arrangement cannot have Bablu and Dawood together.
Hence, Gautam does not sit in the sixth position.
=> Gautam sits in the fifth position and Chintu sits in the fifth position => Emraan sits in the fourth position.
=> Amar can sit in either the first position or the seventh position.
But if Amar sits in the seventh position, Bablu and Dawood cannot sit together. Hence, Amar sits in the first position => Farza sits in the third position.
Dawood's neighbour is not Gautam => Dawood sits in the seventh position and Bablu sits in the sixth Position.
Amar -- Chintu -- Farza -- Emraan -- Gautam -- Bablu -- Dawood
Chintu's neighbours are Amar and Farza.
