sorry...i don't know how to post the pic here...juz want to know if 6R resistor is replaced by a galvanometer which has the internal resistance 6R,what will be the reading?

It depends on the voltage (current ) source connected to the circuit.

Let's say you plug a 1 A source to the entire circuit

I found out solving for the entire thing that the current trough the resistor of 6R is 1/34 R

I wrote KVL for each mini loop, and then wrote KCL at the top, at the bottom and in b). then solved for each current.
