11 u |
8 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
= 11 u - 3 u
= 8 u
8 u = 56
1 u = 56 ÷ 8 = 7
Mass of flour in Shop V in the end
= 3 u
= 3 x 7
= 21 kg
Mass of flour that each shop sold
= 78 - 21
= 57 kg
Amount of flour that both shops sold
= 2 x 57
= 114 kg
Answer(s): 114 kg
