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
= 5 u - 2 u
= 3 u
3 u = 63
1 u = 63 ÷ 3 = 21
Mass of chilli powder in Shop K in the end
= 2 u
= 2 x 21
= 42 kg
Mass of chilli powder that each shop sold
= 69 - 42
= 27 kg
Amount of chilli powder that both shops sold
= 2 x 27
= 54 kg
Answer(s): 54 kg
