The difference between the amount of chilli powder at first and in the end remains unchanged.
Difference in the mass of chilli powder in the end
= 5 u - 2 u
= 3 u
3 u = 69
1 u = 69 ÷ 3 = 23
Mass of chilli powder in Shop J in the end
= 2 u
= 2 x 23
= 46 kg
Mass of chilli powder that each shop sold
= 57 - 46
= 11 kg
Amount of chilli powder that both shops sold
= 2 x 11
= 22 kg
Answer(s): 22 kg
