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 - 2 u
= 5 u
5 u = 70
1 u = 70 ÷ 5 = 14
Mass of bread flour in Shop V in the end
= 2 u
= 2 x 14
= 28 kg
Mass of bread flour that each shop sold
= 62 - 28
= 34 kg
Amount of bread flour that both shops sold
= 2 x 34
= 68 kg
Answer(s): 68 kg
