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 = 63
1 u = 63 ÷ 3 = 21
Mass of flour in Shop V in the end
= 2 u
= 2 x 21
= 42 kg
Mass of flour that each shop sold
= 80 - 42
= 38 kg
Amount of flour that both shops sold
= 2 x 38
= 76 kg
Answer(s): 76 kg
