In the end, all boxes are equal, each box = 360÷3=120g
C left 4/5 →120g after gave 1/5 to A.
4/5→120, therefore, 1/5=120÷4=30g
Total 5/5=150g
A received 30g from C became 120g, therefore A have 90g after gave 1/6 to B.
5/6→90
1/6=90÷5=18g given to B
At 1st, A = 6×18=108g
B received 18g from A
B gave C 1/3, left 2/3=120g
Therefore,1/3 = 60g
B have 180g after received 18g from A.
B at 1st = 180-18 = 162g
C at 1st = 150-60 =90g
Or
C =360 - A - B
C = 360-108-162=90g
C left 4/5 →120g after gave 1/5 to A.
4/5→120, therefore, 1/5=120÷4=30g
Total 5/5=150g
A received 30g from C became 120g, therefore A have 90g after gave 1/6 to B.
5/6→90
1/6=90÷5=18g given to B
At 1st, A = 6×18=108g
B received 18g from A
B gave C 1/3, left 2/3=120g
Therefore,1/3 = 60g
B have 180g after received 18g from A.
B at 1st = 180-18 = 162g
C at 1st = 150-60 =90g
Or
C =360 - A - B
C = 360-108-162=90g
