Total: 360 g
In the end, all same = 360 ÷ 3 = 120 g
C give A 1/5,
C left with 4/5 = 120
1/5 = 120 ÷ 4 = 30
5/5 = 150 g
A have 90 g after give 1/6 to B + 30 g from C = 120 g (in the end)
A left with 5/6 = 90 g
So, 1/6 of A = 90 ÷ 5 = 18 g
Therefore A at 1st (6/6) = 6 x 18 = 108 g
B give C 1/3
B left 2/3 = 120 g
So, 1/3 = 120 ÷ 2 = 60
B have 3/3 = 180 g after receive 1/6=18 g from A
Therefore, B at 1st = 180-18 = 162 g
C at 1st = 150 - 60 =90 g
Or C at 1st = 360 - A -B
= 360 - 108 - 162
= 90 g
Answer:
A = 108 g
A = 162 g
C = 90 g
Hope this helps

Or C at 1st = 360 - A -B
= 360 - 108 - 162
= 90 g
Answer:
A = 108 g
A = 162 g
C = 90 g
