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 = 57
1 u = 57 ÷ 3 = 19
Mass of chicken powder in Shop E in the end
= 2 u
= 2 x 19
= 38 kg
Mass of chicken powder that each shop sold
= 65 - 38
= 27 kg
Amount of chicken powder that both shops sold
= 2 x 27
= 54 kg
Answer(s): 54 kg
