+ 6 u |
+ 2 u |
+ 7.6 u |
| After |
3 p |
1 p |
3 p |
43 + 2 u = 1 p --- (1)
125.8 + 7.6 u =
3 p --- (2)
Make p the same.
(1)
x3 = (3)
129 + 6 u =
3 p --- (3)
(2) = (3)
125.8 + 7.6 u = 129 + 6 u
7.6 u - 6 u = 129 - 125.8
1.6 u = 3.2
1 u = 3.2 ÷ 1.6 = 2
Time taken for the rice flour in Container F to be one-third as much as the rice flour in Container G = 2
Answer(s): 2
