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 = 60
1 u = 60 ÷ 3 = 20
Mass of curry powder in Shop B in the end
= 2 u
= 2 x 20
= 40 kg
Mass of curry powder that each shop sold
= 71 - 40
= 31 kg
Amount of curry powder that both shops sold
= 2 x 31
= 62 kg
Answer(s): 62 kg
