5 u |

The difference between the amount of pepper at first and in the end remains unchanged.
Difference in the mass of pepper in the end
= 5 u - 2 u
= 3 u
3 u = 87
1 u = 87 ÷ 3 = 29
Mass of pepper in Shop U in the end
= 2 u
= 2 x 29
= 58 kg
Mass of pepper that each shop sold
= 60 - 58
= 2 kg
Amount of pepper that both shops sold
= 2 x 2
= 4 kg
Answer(s): 4 kg
