B_wS : B_woS : T_B
= 80 : 20 : 100
= 4 : 1 : 5
= 4(9u+36) : 9u+36 : 5(9u+36)
G_wS : G_woS : T_G
= 55 : 45 : 100
= 11 : 9 : 20
20u+5(9u+36) = 700
4u+9u+36 = 140
u = (140-36)÷(4+9) = 8
9u+36
= 9×8+36
= 108 (Ans)
= 80 : 20 : 100
= 4 : 1 : 5
= 4(9u+36) : 9u+36 : 5(9u+36)
G_wS : G_woS : T_G
= 55 : 45 : 100
= 11 : 9 : 20
20u+5(9u+36) = 700
4u+9u+36 = 140
u = (140-36)÷(4+9) = 8
9u+36
= 9×8+36
= 108 (Ans)
