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 - 3 u
= 8 u
8 u = 72
1 u = 72 ÷ 8 = 9
Mass of rice flour in Shop R in the end
= 3 u
= 3 x 9
= 27 kg
Mass of rice flour that each shop sold
= 53 - 27
= 26 kg
Amount of rice flour that both shops sold
= 2 x 26
= 52 kg
Answer(s): 52 kg
