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 - 3 u
= 8 u
8 u = 72
1 u = 72 ÷ 8 = 9
Mass of bread flour in Shop E in the end
= 3 u
= 3 x 9
= 27 kg
Mass of bread flour that each shop sold
= 61 - 27
= 34 kg
Amount of bread flour that both shops sold
= 2 x 34
= 68 kg
Answer(s): 68 kg
