An ammeter and a voltmeter are connected...

An ammeter and a voltmeter are connected in series to a battery with an emf `xi = 6.0 V`. When a certain resistance is connected in parallel with the voltmeter, the readings of the latter decreases `eta = 2.0` times, whereas the readings of the ammeter increase the same number of times, Find the voltmeter readings after the connection of the resistance.
