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 = 54
1 u = 54 ÷ 3 = 18
Mass of chilli powder in Shop D in the end
= 2 u
= 2 x 18
= 36 kg
Mass of chilli powder that each shop sold
= 72 - 36
= 36 kg
Amount of chilli powder that both shops sold
= 2 x 36
= 72 kg
Answer(s): 72 kg
