Total resistance of diagram​

Answer»

3R/4Method :If you observe closely, there are few wires which doesn't have any resistors CONNECTED across it        Which means that the POTENTIAL is same throughout the wireI.e. across D and C, the 2 resistors are connected in parallel and SIMILARLY  resistors between E and F are connected parallelAfter this, you just add up the resistances in parallel and SERIES accordinglyHope this ANSWER helped you :)
