Fraction of chilli powder left after using

19 =
89 Amount of chilli powder left after using some = 8 u
Amount of chilli powder after buying 24 kg of chilli powder = 8 u + 24
8 u + 24 = 11 u
11 u - 8 u = 24
3 u = 24
1 u = 24 ÷ 3 = 8
Amount of chilli powder that Mrs Chium had at first
= 9 u
= 9 x 8
= 72 kg
