at first
B:G:G-B = 1:4:3 = 1u:4u:3u
in the end
B:G:G-B = 1:2:1 = 1u+12:4u-12:3u-24
1u+12 = 3u-24
u = (12+24)÷(3-1) = 18
G+B = 1u+4u
= 5u = 5×18 = 90 (Ans)
B:G:G-B = 1:4:3 = 1u:4u:3u
in the end
B:G:G-B = 1:2:1 = 1u+12:4u-12:3u-24
1u+12 = 3u-24
u = (12+24)÷(3-1) = 18
G+B = 1u+4u
= 5u = 5×18 = 90 (Ans)
