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 = 45
1 u = 45 ÷ 9 = 5
Mass of bread flour in Shop E in the end
= 2 u
= 2 x 5
= 10 kg
Mass of bread flour that each shop sold
= 80 - 10
= 70 kg
Amount of bread flour that both shops sold
= 2 x 70
= 140 kg
Answer(s): 140 kg
