Book tatkal tkt from ahemadnagar to bangalore in KTK exp if you are not going to Hyderabad for work and only for transit.
Otherwise start with devgiri exp on 11th Morning, reach SC by afternoon, take either Rajdhani or Garib rath from SC or any other suitable train from KCG in evening and reach Bangalore by 12th morning but it will be unnecessarily hectic journey.
Ahamadnagr to SBC is best option.
