Explanation / Answer

here,

R2 , R3 , R4 and R5 are in parallel, let their equivalent resisatnce be R1'

1/R1' = 1/R2 + 1/R3 + 1/R4 + 1/R5

1/R1' = 1/282 + 1/763 + 1/534 + 1/165

R' = 78.2 ohm

current through battery , I1 = V/(R1 + R1')

I1 = 64.5 /( 611 + 78.2)

I1 = 9.36 * 10^-2 A

the current at H , Ih = ( V - I1 * R1)/R5

Ih = ( 64.5 - 0.0936 * 611)/(165)

Ih = 0.044 A = 44 mA

Ic = Ih + ( V - I1 * R1)/R4

Ic = 0.44 + ( 64.5 - 0.0936 * 611)/(534)

Ic = 0.0577 A = 57.7 mA

If = I1 - ( V - I1 * R1)/R2

If = 0.0936 - ( 64.5 - 0.0936 * 611)/(282)

If = 0.0678 A = 67.8 mA
