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 = 51
1 u = 51 ÷ 3 = 17
Mass of curry powder in Shop H in the end
= 2 u
= 2 x 17
= 34 kg
Mass of curry powder that each shop sold
= 78 - 34
= 44 kg
Amount of curry powder that both shops sold
= 2 x 44
= 88 kg
Answer(s): 88 kg
