Expert Answer:

Since resistivity of material of wire_B is less than that of wire-A, Wire_A has to be thicker.

hece current drawn from battery is 6V/3Ω is 2A
 
Since all the resistance are connected in parallel, potenial difference across each resistance has to be 6V
 
Hence current through 30Ω resistance = 6/30 = 0.2 A
current through 10Ω resistance = 6/10 = 0.6 A
current through 5Ω resistance = 6/5 = 1.2 A
