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
= 11 u - 3 u
= 8 u
8 u = 88
1 u = 88 ÷ 8 = 11
Mass of chicken powder in Shop X in the end
= 3 u
= 3 x 11
= 33 kg
Mass of chicken powder that each shop sold
= 50 - 33
= 17 kg
Amount of chicken powder that both shops sold
= 2 x 17
= 34 kg
Answer(s): 34 kg
