Six passengers Sony, Kenny, Tony, Lenny, Mony and Jonny joined the pre-existence queue to book their railway ticket at 'XYZ' railway station. They all lined up together in such a way that Kenny is between Jonny and Lenny. Mony is between Sony and Tony. Sony doesn't stand next to either Jonny or Lenny. Tony doesn't stand next to Lenny.
Who is standing at immediate back of Kenny if Sony is not standing after him in the queue?
