If I were you, I would take the direct flight from BLR to SIN on AI/IA. The flight is not bad at all as long as you are in J. Too many connections in India is a bad thing

Since OP only has a few days.. a direct flight from DEL or BLR to SIN would be
ideal. no need to go on a mileage run here.. plus a transfer between
International and domestic terminals is not the easiest things
at BOM and DEL..
I wouldnt recommend BLR-BOM-HKG-SIN while you can easily do BLR-SIN.
Efrem I missed on the # of days thing..
