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 = 63
1 u = 63 ÷ 3 = 21
Mass of chicken powder in Shop E in the end
= 2 u
= 2 x 21
= 42 kg
Mass of chicken powder that each shop sold
= 78 - 42
= 36 kg
Amount of chicken powder that both shops sold
= 2 x 36
= 72 kg
Answer(s): 72 kg
