an ammeter and a voltmeter are connected in series to a battery with an emf of 6v.when a certain resistance is connected in parallel with the voltmeter,reading of the latter decreases two times,while reading of the ammeter increases the same no. of times.find the voltmeter reading after the connection of the resistance???

Let the resistance of the voltmeter, shunt and ammeter be x, y and z ohm respectively. Current in the 1st ckt = i1

Current in the 2nd ckt = i2
