7 u |

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 = 80
1 u = 80 ÷ 4 = 20
Mass of rice flour in Shop T in the end
= 3 u
= 3 x 20
= 60 kg
Mass of rice flour that each shop sold
= 61 - 60
= 1 kg
Amount of rice flour that both shops sold
= 2 x 1
= 2 kg
Answer(s): 2 kg
