How to calculate total current?

1 amp = 1000 mA.
0.021 A = 21 mA.
0.021 A = 21 mA.

@Kishu is right. We can't connect volt and ammeters directly because their will be short circuit.

Here we have a total current of the 21m amp,
Current across R1is.
I1=v/R1=12/1*10^3=12m amp
Current across R2 is;
I2=v/R2=12/2*10^3=6m amp,
Remaining current is 3m amp.
Then current across R4 is,
I3=v/R4=12/2*10^3=3m amp,
Hence resistor R3 is open circuit.
