The difference between the amount of bread flour at first and in the end remains unchanged.
Difference in the mass of bread flour in the end
= 7 u - 2 u
= 5 u
5 u = 80
1 u = 80 ÷ 5 = 16
Mass of bread flour in Shop X in the end
= 2 u
= 2 x 16
= 32 kg
Mass of bread flour that each shop sold
= 59 - 32
= 27 kg
Amount of bread flour that both shops sold
= 2 x 27
= 54 kg
Answer(s): 54 kg
