The difference between the amount of chilli powder at first and in the end remains unchanged.
Difference in the mass of chilli powder in the end
= 7 u - 3 u
= 4 u
4 u = 76
1 u = 76 ÷ 4 = 19
Mass of chilli powder in Shop F in the end
= 3 u
= 3 x 19
= 57 kg
Mass of chilli powder that each shop sold
= 71 - 57
= 14 kg
Amount of chilli powder that both shops sold
= 2 x 14
= 28 kg
Answer(s): 28 kg
