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 = 90
1 u = 90 ÷ 9 = 10
Mass of chicken powder in Shop D in the end
= 2 u
= 2 x 10
= 20 kg
Mass of chicken powder that each shop sold
= 52 - 20
= 32 kg
Amount of chicken powder that both shops sold
= 2 x 32
= 64 kg
Answer(s): 64 kg
