In series connection, the current across all the resister is same. So to get the answer. See above solutions.

But they asked to calculate current at 680 v right?

Equivalent resistance Req = 470+680+1000+1200 = 3350 ohms
"All are connected in series" and
we know that current (I) is same Series connection.
So I=V/Req = 20/3350
I = 6 mA.

Series current is same, but voltage drop across all the resistors are different.
Here total voltage 20v.
R=680 ohms, 470, 1200, 1000.
Ohms law V=IR.
I = 20/3.35k.
= 5.97 milli amps.

Total resistors =470/1000+680/1000+1+1. 2=3. 35 kohms.
Voltage = 20V.
V=IR.
I=V/R.
=20/3. 35k.
I=5. 97mA.
Voltage = 20V.
V=IR.
I=V/R.
=20/3. 35k.
I=5. 97mA.

Because in series current through all resistor are same.

Total resistors = 470 + 680 + 1k + 1.2K = 3.35 kohms
V=20v
V=IR
20=I*3.35
I=20/3.35K
I=5.97mA
which is equal to 6mA
V=20v
V=IR
20=I*3.35
I=20/3.35K
I=5.97mA
which is equal to 6mA
