2 u |
7 u |
5 u |
The difference between the amount of flour at first and in the end remains unchanged.
Difference in the mass of flour in the end
= 7 u - 2 u
= 5 u
5 u = 60
1 u = 60 ÷ 5 = 12
Mass of flour in Shop D in the end
= 2 u
= 2 x 12
= 24 kg
Mass of flour that each shop sold
= 64 - 24
= 40 kg
Amount of flour that both shops sold
= 2 x 40
= 80 kg
Answer(s): 80 kg
