Total resistance of the circuit 
⇒ ⇒ Main current 
Combination of voltmeter and 80 Ω Ω resistance is connected in series with 20 Ω Ω , so current through 20 Ω Ω and this combination will be same 
.
Since the resistance of voltmeter is also 80 Ω Ω , so this current is equally distributed in 80 Ω Ω resistance and voltmeter (i.e. 
through each)
P.D. across 80 Ω Ω resistance
