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 - 2 u
= 5 u
5 u = 75
1 u = 75 ÷ 5 = 15
Mass of rice flour in Shop X in the end
= 2 u
= 2 x 15
= 30 kg
Mass of rice flour that each shop sold
= 74 - 30
= 44 kg
Amount of rice flour that both shops sold
= 2 x 44
= 88 kg
Answer(s): 88 kg
