Container T and Container U had 48 kg of chilli powder and 133.6 kg of chilli powder respectively.

+ 6 u |

3 p |

48 + 2 u = 1 p --- (1)
133.6 + 8.6 u =
3 p --- (2)
Make p the same.
(1)
x3 = (3)
144 + 6 u =
3 p --- (3)
(2) = (3)
133.6 + 8.6 u = 144 + 6 u
8.6 u - 6 u = 144 - 133.6
2.6 u = 10.4
1 u = 10.4 ÷ 2.6 = 4
Time taken for the chilli powder in Container T to be one-third as much as the chilli powder in Container U = 4
