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 = 72
1 u = 72 ÷ 4 = 18
Mass of chicken powder in Shop R in the end
= 3 u
= 3 x 18
= 54 kg
Mass of chicken powder that each shop sold
= 62 - 54
= 8 kg
Amount of chicken powder that both shops sold
= 2 x 8
= 16 kg
Answer(s): 16 kg
