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
= 7 u - 2 u
= 5 u
5 u = 55
1 u = 55 ÷ 5 = 11
Mass of chicken powder in Shop X in the end
= 2 u
= 2 x 11
= 22 kg
Mass of chicken powder that each shop sold
= 68 - 22
= 46 kg
Amount of chicken powder that both shops sold
= 2 x 46
= 92 kg
Answer(s): 92 kg
