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
= 11 u - 3 u
= 8 u
8 u = 80
1 u = 80 ÷ 8 = 10
Mass of curry powder in Shop G in the end
= 3 u
= 3 x 10
= 30 kg
Mass of curry powder that each shop sold
= 50 - 30
= 20 kg
Amount of curry powder that both shops sold
= 2 x 20
= 40 kg
Answer(s): 40 kg
