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
= 5 u - 2 u
= 3 u
3 u = 69
1 u = 69 ÷ 3 = 23
Mass of chicken powder in Shop C in the end
= 2 u
= 2 x 23
= 46 kg
Mass of chicken powder that each shop sold
= 51 - 46
= 5 kg
Amount of chicken powder that both shops sold
= 2 x 5
= 10 kg
Answer(s): 10 kg
