Overload or not?

The normal North American residential power grid supplies three-wire split-phase 120/240 V 60 Hz Ac power. A frequently used arrangement to supply power to standard duplex type receptacle is to make use of a common neutral wire in a three wire split receptacle arrangement.

The schematic above illustrates a split receptacle outlet with a toaster and an electric frying pan plugged into the two outlets.

What is the current flow through the neutral wire in the circuit show in the above schematic?
