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 - 3 u
= 2 u
2 u = 50
1 u = 50 ÷ 2 = 25
Mass of bread flour in Shop B in the end
= 3 u
= 3 x 25
= 75 kg
Mass of bread flour that each shop sold
= 76 - 75
= 1 kg
Amount of bread flour that both shops sold
= 2 x 1
= 2 kg
Answer(s): 2 kg
