Thanks for the hint. So because the 30kOhm resistor is in series with an open circuit, no current flows through it, therefore there is no voltage drop and we can ignore it from the equation?

I found how to get the solution to this question (the answer is 200V), but I don't understand why we ignore the 30kOhm resistor when using analysing the circuit. Because it is in series with the open voltage, wouldn't there be some voltage drop across the resistor that would affect the...
