The difference between the amount of chicken powder at first and in the end remains unchanged.
Difference in the mass of chicken powder in the end
= 11 u - 3 u
= 8 u
8 u = 72
1 u = 72 ÷ 8 = 9
Mass of chicken powder in Shop F in the end
= 3 u
= 3 x 9
= 27 kg
Mass of chicken powder that each shop sold
= 58 - 27
= 31 kg
Amount of chicken powder that both shops sold
= 2 x 31
= 62 kg
Answer(s): 62 kg
