Container T and Container U had 38 kg of bread flour and 103.6 kg of bread flour respectively. If 2 kg of bread flour and 7.3 kg of bread flour are added into Container T and Container U every day, how many days later will the bread flour in Container T be one-third as much as the bread flour in Container U?

+ 6 u |
+ 2 u |
+ 7.3 u |
| After |
3 p |
1 p |
3 p |
38 + 2 u = 1 p --- (1)
103.6 + 7.3 u =
3 p --- (2)
Make p the same.
(1)
x3 = (3)
114 + 6 u =
3 p --- (3)
(2) = (3)
103.6 + 7.3 u = 114 + 6 u
7.3 u - 6 u = 114 - 103.6
1.3 u = 10.4
1 u = 10.4 ÷ 1.3 = 8
Time taken for the bread flour in Container T to be one-third as much as the bread flour in Container U = 8
Answer(s): 8
