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 = 57
1 u = 57 ÷ 3 = 19
Mass of chilli powder in Shop D in the end
= 2 u
= 2 x 19
= 38 kg
Mass of chilli powder that each shop sold
= 78 - 38
= 40 kg
Amount of chilli powder that both shops sold
= 2 x 40
= 80 kg
Answer(s): 80 kg
