Ratio of currents in R1,R2,R3 is i1 :i2 :i 3 = (1/R1) :(1/R2):(1/R3)
= (1/4) :(1/6) :(1/7)
= (84/4) :(84/6) :(84/7)
= 21 : 14 : 12
So, i1 = Io [(21)/(21+14+12)]
= Io[21/47]
= 0.4468 Io
i2 = Io [(14)/(21+14+12)]
= Io[14/47]
= 0.2978 Io
i3 = Io [(12)/(21+14+12)]
= Io[12/47]
= 0.2553 Io
(b). Same as part(a)
