g/3 +b/2 =205
g/2 + b = 370
2g/3 +b =410
g/2 + b = 370
4g/6 +b =410
3g/6 + b = 370
------------------------ subtract
g/6 = 40
g = 240
b = 370 - 120 = 250
g + b = 490 ?
g/2 + b = 370
2g/3 +b =410
g/2 + b = 370
4g/6 +b =410
3g/6 + b = 370
------------------------ subtract
g/6 = 40
g = 240
b = 370 - 120 = 250
g + b = 490 ?
