The difference between the amount of curry powder at first and in the end remains unchanged.
Difference in the mass of curry powder in the end
= 5 u - 2 u
= 3 u
3 u = 57
1 u = 57 ÷ 3 = 19
Mass of curry powder in Shop S in the end
= 2 u
= 2 x 19
= 38 kg
Mass of curry powder that each shop sold
= 80 - 38
= 42 kg
Amount of curry powder that both shops sold
= 2 x 42
= 84 kg
Answer(s): 84 kg
