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 = 90
1 u = 90 ÷ 5 = 18
Mass of chilli powder in Shop K in the end
= 2 u
= 2 x 18
= 36 kg
Mass of chilli powder that each shop sold
= 52 - 36
= 16 kg
Amount of chilli powder that both shops sold
= 2 x 16
= 32 kg
Answer(s): 32 kg
