If yes, then you will be handed your MAA-BLR boarding pass as well when you check-in for your SIN-MAA flight and your bags will be through checked-in to BLR.
I'm not quite sure if Jet will do this for seperate PNR numbers but I'm sure the senior members here will be able to help you out.
Is this due to customs where you're required to pick up your luggage, conduct the customs due diligence and recheck your bags?
