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 - 2 u
= 9 u
9 u = 81
1 u = 81 ÷ 9 = 9
Mass of curry powder in Shop V in the end
= 2 u
= 2 x 9
= 18 kg
Mass of curry powder that each shop sold
= 68 - 18
= 50 kg
Amount of curry powder that both shops sold
= 2 x 50
= 100 kg
Answer(s): 100 kg
