Voltage of a complex pararell circuit
The capacitors don't conduct when the supply is pure DC so ignore them. Next use ohms law to calculate current through R11 and R12. Hint Rtotal = R11+R12.

Next calculate the voltage across R12 given that current you just calculated.

Or, you can just simply look at it and notice that R11 and R12 are the same value hence the voltage at their midpoint is half of 1.5V
