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 - 3 u
= 4 u
4 u = 76
1 u = 76 ÷ 4 = 19
Mass of bread flour in Shop Q in the end
= 3 u
= 3 x 19
= 57 kg
Mass of bread flour that each shop sold
= 74 - 57
= 17 kg
Amount of bread flour that both shops sold
= 2 x 17
= 34 kg
Answer(s): 34 kg
