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
= 5 u - 2 u
= 3 u
3 u = 48
1 u = 48 ÷ 3 = 16
Mass of bread flour in Shop L in the end
= 2 u
= 2 x 16
= 32 kg
Mass of bread flour that each shop sold
= 74 - 32
= 42 kg
Amount of bread flour that both shops sold
= 2 x 42
= 84 kg
Answer(s): 84 kg
