Explanation / Answer
B and C are in parallel so their effective resistance =R/2 now A and combination of Band are in series so the resistance =R+R/2=3R/2 this combination and D are in parallel so the total resistance=[R*3R/2] /5R/2=3R/5 current in the circuit=V/R=V/3R/5=5V/3R current through the combination of A and B and C=5V/3R*R/5R/2=2V/3R now current through D is 5V/3R-2V/3R=V/R current after passing through A splits into two parts at the end ofA now current through B=2V/3R*R/2R=2V/6R and the current through C =2V/6R now ranking current through A=2V/3R current through B=2V/6R current through C=2V/6R current through D=V/R largest to smallest D,A,C,B B and C are equal
