When we place a voltmeter across a single battery which is connected to another battery in series, does voltmeter show the emf of the single battery or the sum of emf of both the batteries?

Why not draw out the circuit and work it out?
Recall that a real battery is modeled by an ideal battery in series with a small resistance.
