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 = 75
1 u = 75 ÷ 3 = 25
Mass of chicken powder in Shop T in the end
= 2 u
= 2 x 25
= 50 kg
Mass of chicken powder that each shop sold
= 55 - 50
= 5 kg
Amount of chicken powder that both shops sold
= 2 x 5
= 10 kg
Answer(s): 10 kg
