2 u |
5 u |
3 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
= 5 u - 2 u
= 3 u
3 u = 60
1 u = 60 ÷ 3 = 20
Mass of flour in Shop Q in the end
= 2 u
= 2 x 20
= 40 kg
Mass of flour that each shop sold
= 66 - 40
= 26 kg
Amount of flour that both shops sold
= 2 x 26
= 52 kg
Answer(s): 52 kg
