Branch current issues

Hello all, first post here so be gentle

Basically by problem is that im trying to work out the current in the branches of the circuit. I understand that the branch current should be the supply voltage divided by the total branch resistance (I= V/R) but every time I try that and add both branch together to get the total current of the circuit, its coming out at twice as much as it should be. I worked out the total current to be 50mA but when I work out the branch currents and add them together, it gives me a total of 100mA. Any useful bits of information would be greatly appreciated.

Chick.

 

Just a bit of spare work I had lying round from college, thought I would give it a go.
50mA of current would be flowing through R1 and R6 as they are in series. But the current would split to go through the separate branches of of the parallel resistors.
The voltage across the resistors would be:
R1= 2
R5= 4.5
R6= 3.5
I'm not to sure how to proceed from this point...

 

Suddenly realized how obvious that was now, thank you for pointing that out!
