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 = 52
1 u = 52 ÷ 4 = 13
Mass of curry powder in Shop V in the end
= 3 u
= 3 x 13
= 39 kg
Mass of curry powder that each shop sold
= 77 - 39
= 38 kg
Amount of curry powder that both shops sold
= 2 x 38
= 76 kg
Answer(s): 76 kg
