Dear studnent,

Current due to movement of sodium ions= $I_{Na}=neAv_{Na}$
Current due to movement of cholride ions= $I_{Cl}=neAv_{Cl}$
The two currents will be in the same direction since ions with opposite charges will move in opposite directions.

Hence total current flowing through the salt water= $neA(v_{Na}+v_{Cl})$

The fig. Shows a network of resistance in which the point A is earthed
