8.2 + 0.125 = 8.325, how this stem comes?

Vz = 8.2 V.
Rs = 5 ohms.
Is = 25 mA = 0.025 A.
Vs = Is x Rs.
= 0.025 x 5 = 0.125 V.
Vin = Vz+Vs.
= 8.2 V + 0.125 V.
= 8.325 V answer.
Rs = 5 ohms.
Is = 25 mA = 0.025 A.
Vs = Is x Rs.
= 0.025 x 5 = 0.125 V.
Vin = Vz+Vs.
= 8.2 V + 0.125 V.
= 8.325 V answer.

Voltage drop across 5 ohm is 5*25mA = 125mV
Then total voltage across terminal is 8.2+.125 = 8.325
Then total voltage across terminal is 8.2+.125 = 8.325
