Resistance in kilo ohm and answer in volt.

Unkown output voltage means voltage drop across the last element. Here bothresistance value is same so 12v is coming.

We know voltage in one of the 68 ohm resistor is V=I.R1(R1=resistance of one of the resistors )
again V=(V/R).R1(R=total resistance of circuit.)
Hence,V=[24/(68+68)]*68=12V
Voltage divider rule is applicable for series circuit only because in series only voltage varies but not in paralel circuits.

24V is divided into two part each= 24/2 = 12V
