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
= 7 u - 3 u
= 4 u
4 u = 72
1 u = 72 ÷ 4 = 18
Mass of curry powder in Shop L in the end
= 3 u
= 3 x 18
= 54 kg
Mass of curry powder that each shop sold
= 73 - 54
= 19 kg
Amount of curry powder that both shops sold
= 2 x 19
= 38 kg
Answer(s): 38 kg
