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 = 60
1 u = 60 ÷ 5 = 12
Mass of chicken powder in Shop S in the end
= 2 u
= 2 x 12
= 24 kg
Mass of chicken powder that each shop sold
= 72 - 24
= 48 kg
Amount of chicken powder that both shops sold
= 2 x 48
= 96 kg
Answer(s): 96 kg
