2 u |
11 u |
9 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 - 2 u
= 9 u
9 u = 54
1 u = 54 ÷ 9 = 6
Mass of flour in Shop N in the end
= 2 u
= 2 x 6
= 12 kg
Mass of flour that each shop sold
= 71 - 12
= 59 kg
Amount of flour that both shops sold
= 2 x 59
= 118 kg
Answer(s): 118 kg
