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
= 11 u - 2 u
= 9 u
9 u = 72
1 u = 72 ÷ 9 = 8
Mass of bread flour in Shop C in the end
= 2 u
= 2 x 8
= 16 kg
Mass of bread flour that each shop sold
= 76 - 16
= 60 kg
Amount of bread flour that both shops sold
= 2 x 60
= 120 kg
Answer(s): 120 kg
