3 u |
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 = 72
1 u = 72 ÷ 8 = 9
Mass of flour in Shop J in the end
= 3 u
= 3 x 9
= 27 kg
Mass of flour that each shop sold
= 55 - 27
= 28 kg
Amount of flour that both shops sold
= 2 x 28
= 56 kg
Answer(s): 56 kg
