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 - 3 u
= 4 u
4 u = 48
1 u = 48 ÷ 4 = 12
Mass of chicken powder in Shop M in the end
= 3 u
= 3 x 12
= 36 kg
Mass of chicken powder that each shop sold
= 80 - 36
= 44 kg
Amount of chicken powder that both shops sold
= 2 x 44
= 88 kg
Answer(s): 88 kg
