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 = 60
1 u = 60 ÷ 4 = 15
Mass of chilli powder in Shop V in the end
= 3 u
= 3 x 15
= 45 kg
Mass of chilli powder that each shop sold
= 65 - 45
= 20 kg
Amount of chilli powder that both shops sold
= 2 x 20
= 40 kg
Answer(s): 40 kg
