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 = 96
1 u = 96 ÷ 8 = 12
Mass of chicken powder in Shop J in the end
= 3 u
= 3 x 12
= 36 kg
Mass of chicken powder that each shop sold
= 51 - 36
= 15 kg
Amount of chicken powder that both shops sold
= 2 x 15
= 30 kg
Answer(s): 30 kg
