The difference between the amount of pepper at first and in the end remains unchanged.
Difference in the mass of pepper in the end
= 11 u - 2 u
= 9 u
9 u = 63
1 u = 63 ÷ 9 = 7
Mass of pepper in Shop X in the end
= 2 u
= 2 x 7
= 14 kg
Mass of pepper that each shop sold
= 80 - 14
= 66 kg
Amount of pepper that both shops sold
= 2 x 66
= 132 kg
Answer(s): 132 kg
