Since resistances B and C are connected in parallel,
Current, I = V/(9 + (B || C))
2 = V/(9 + (B || C)) ....... (1)
IB = 2C/(B + C)
2C = 1.5 B + 1.5 C
C = 3B
Equivalent resistance of B and C,
B || C = BC/(B + C) = 3B^2/4B = 0.75B
From equation (1)
2 = V/(9 + 0.75B) ...... (2)
Since total current, I = 0.75 + 0.25 = 1 A
V - 0.75B = 1 ...... (3)
From equation (2) and (3)
Resistance, RB = 12 ohm
