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 = 75
1 u = 75 ÷ 3 = 25
Mass of curry powder in Shop B in the end
= 2 u
= 2 x 25
= 50 kg
Mass of curry powder that each shop sold
= 64 - 50
= 14 kg
Amount of curry powder that both shops sold
= 2 x 14
= 28 kg
Answer(s): 28 kg
