b =  132000
c =  88000

Solution:

k1=77+6+4=717≐0.4118 k2=67+6+4=617≐0.3529 k3=47+6+4=417≐0.2353  t=286000  z=t/(k1+k2)=286000/(0.4118+0.3529)=374000 a=z⋅ k1=374000⋅ 0.4118≐154000=154000k_{ 1 } = \dfrac{ 7 }{ 7+6+4 } = \dfrac{ 7 }{ 17 } \doteq 0.4118 \ \\ k_{ 2 } = \dfrac{ 6 }{ 7+6+4 } = \dfrac{ 6 }{ 17 } \doteq 0.3529 \ \\ k_{ 3 } = \dfrac{ 4 }{ 7+6+4 } = \dfrac{ 4 }{ 17 } \doteq 0.2353 \ \\ \ \\ t = 286000 \ \\ \ \\ z = t/(k_{ 1 }+k_{ 2 }) = 286000/(0.4118+0.3529) = 374000 \ \\ a = z \cdot \ k_{ 1 } = 374000 \cdot \ 0.4118 \doteq 154000 = 154000
b=z⋅ k2=374000⋅ 0.3529≐132000=132000b = z \cdot \ k_{ 2 } = 374000 \cdot \ 0.3529 \doteq 132000 = 132000
c=z⋅ k3=374000⋅ 0.2353=88000c = z \cdot \ k_{ 3 } = 374000 \cdot \ 0.2353 = 88000
