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 = 45
1 u = 45 ÷ 3 = 15
Mass of pepper in Shop V in the end
= 2 u
= 2 x 15
= 30 kg
Mass of pepper that each shop sold
= 77 - 30
= 47 kg
Amount of pepper that both shops sold
= 2 x 47
= 94 kg
Answer(s): 94 kg
