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
= 11 u - 2 u
= 9 u
9 u = 63
1 u = 63 ÷ 9 = 7
Mass of rice flour in Shop S in the end
= 2 u
= 2 x 7
= 14 kg
Mass of rice flour that each shop sold
= 67 - 14
= 53 kg
Amount of rice flour that both shops sold
= 2 x 53
= 106 kg
Answer(s): 106 kg
