aaaaaaaaaaaaa

 

Does redrawing it like this help?

 

60 and 30 are in parallel

Check that last bit again!

 

yeah that definitely makes it easier to see!

20 and 40 are in series, making 60, then 60 and 60 are in parallel, making 30, and finally, 60 and 30 are in parallel leaving 20

using V=IR my voltage across it is 200

Thanks!

You apparently know the answer, because, although 200V is correct, your reasoning is flawed.
