see shailly first of all u will have to take the total resistance ...voltage is given therefore apply V=IR.......the current u get is the ammeter reading........in the first resistor resistance is given and current(as it is the same for all in a series circuit)....so again apply V=IR where u would get the voltage which is the voltmeter reading..........JUST TRY IT ONCE U WOULD BE GETTING 0.5 FOR BOTH
