7 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
= 7 u - 3 u
= 4 u
4 u = 48
1 u = 48 ÷ 4 = 12
Mass of pepper in Shop H in the end
= 3 u
= 3 x 12
= 36 kg
Mass of pepper that each shop sold
= 73 - 36
= 37 kg
Amount of pepper that both shops sold
= 2 x 37
= 74 kg
Answer(s): 74 kg
