Vout=(R2/(R1+R2))Vin for a voltage divider,when a input voltage is applied across a series of resistors R1&R2 and ouput is the voltage applied across R2.
here,Vin=24V,R1=R2=68ohms,
so,Vout=(68/(68+68))24
=12V
here,Vin=24V,R1=R2=68ohms,
so,Vout=(68/(68+68))24
=12V

In a voltage divider circuit there are always 2 resistors in series say r1 nd r2.
The output is taken across say r2.
Then the output voltage will be;
Vo=(r2/r2+r1)vi.
Vi is input voltage.
Therefore;
Vo=(68/68+68)24=24/2=12.
The output is taken across say r2.
Then the output voltage will be;
Vo=(r2/r2+r1)vi.
Vi is input voltage.
Therefore;
Vo=(68/68+68)24=24/2=12.

Voltage divider general formula:
Vout = (Z2/(Z1+Z2))*Vin.
Vout = (68/136)*24.
Vout = (1/2)*24.
Vout = 12.
Vout = (Z2/(Z1+Z2))*Vin.
Vout = (68/136)*24.
Vout = (1/2)*24.
Vout = 12.

1st draw the circuit diagram of the question then you will get the answer simply by observing the circuit diagram.

It is totally wrong because output voltage means consumed voltage except source so answer is 24.

He is not specifying individual divider o/p voltage. He ask only o/p voltage means 24v(consumed at series resistors).

Where we need to calculate output?
