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 = 80
1 u = 80 ÷ 8 = 10
Mass of chicken powder in Shop T in the end
= 3 u
= 3 x 10
= 30 kg
Mass of chicken powder that each shop sold
= 66 - 30
= 36 kg
Amount of chicken powder that both shops sold
= 2 x 36
= 72 kg
Answer(s): 72 kg
