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 - 2 u
= 5 u
5 u = 65
1 u = 65 ÷ 5 = 13
Mass of chilli powder in Shop H in the end
= 2 u
= 2 x 13
= 26 kg
Mass of chilli powder that each shop sold
= 73 - 26
= 47 kg
Amount of chilli powder that both shops sold
= 2 x 47
= 94 kg
Answer(s): 94 kg
