3 u |
5 u |
2 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 - 3 u
= 2 u
2 u = 48
1 u = 48 ÷ 2 = 24
Mass of flour in Shop E in the end
= 3 u
= 3 x 24
= 72 kg
Mass of flour that each shop sold
= 76 - 72
= 4 kg
Amount of flour that both shops sold
= 2 x 4
= 8 kg
Answer(s): 8 kg
