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 = 54
1 u = 54 ÷ 3 = 18
Mass of chicken powder in Shop W in the end
= 2 u
= 2 x 18
= 36 kg
Mass of chicken powder that each shop sold
= 77 - 36
= 41 kg
Amount of chicken powder that both shops sold
= 2 x 41
= 82 kg
Answer(s): 82 kg
