The difference between the amount of rice flour at first and in the end remains unchanged.
Difference in the mass of rice flour in the end
= 7 u - 3 u
= 4 u
4 u = 76
1 u = 76 ÷ 4 = 19
Mass of rice flour in Shop V in the end
= 3 u
= 3 x 19
= 57 kg
Mass of rice flour that each shop sold
= 64 - 57
= 7 kg
Amount of rice flour that both shops sold
= 2 x 7
= 14 kg
Answer(s): 14 kg
