After |
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 = 85
1 u = 85 ÷ 5 = 17
Mass of flour in Shop V in the end
= 2 u
= 2 x 17
= 34 kg
Mass of flour that each shop sold
= 53 - 34
= 19 kg
Amount of flour that both shops sold
= 2 x 19
= 38 kg
Answer(s): 38 kg
