How to calculate Vout that will be displayed on the multimeter, which has an internal resistance of 70kΩ

Vin = 17v
R1 = 30kΩ
R2 = 5kΩ

I know the formula to calculate Vout but I have no idea where to put the 70kΩ.

Treat your multimeter like a resistor in parallel with your load resistors. This will create 2 resistors in parallel, 30kΩ + 5kΩ = 35kΩ and 70kΩ. Then you can find the current flowing through each leg, and from that obtain the voltage across each.

Here is the exact question.

Calculate the Vout value that will be displayed on a multimeter with an internal resiatance of 70kΩ where:

Vin = 17v

R1 = 30kΩ

R2 = 5kΩ

Anster to at least 3 decimal places.

Is this from a textbook? Or was this generated by a teacher? If it is the former, could you post a screenshot of the question? If it is the latter, then your teacher will have to provide more information for this to be solvable.

If it is randomly generated, then it is almost certainly referring to a diagram that defined the configuration and the variables and the random generation is just coming up with specific values for the problem.
