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 - 2 u
= 9 u
9 u = 81
1 u = 81 ÷ 9 = 9
Mass of chicken powder in Shop H in the end
= 2 u
= 2 x 9
= 18 kg
Mass of chicken powder that each shop sold
= 58 - 18
= 40 kg
Amount of chicken powder that both shops sold
= 2 x 40
= 80 kg
Answer(s): 80 kg
