The circuit shows the total power of all resistors equals the power that the power supply is producing.  Power is measured in Watts, and Watts is Voltage times Current.  P is VI.   The supply is 50 Volts times 6 Amps which is 300 Watts.   The 20 Ohm resistor is 20 Volts and 1 Amp which is 20 Watts.  The 30 Ohm resistor is 30 Volts and 1 Amp which is 30 Watts.  The 10 Ohm resistor is 50 Volts and 5 Amps which is 250 Watts.   The total power is 20 Watts + 30 Watts + 250 Watts which is 300 Watts.
