3 u |
7 u |
4 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 = 72
1 u = 72 ÷ 4 = 18
Mass of pepper in Shop J in the end
= 3 u
= 3 x 18
= 54 kg
Mass of pepper that each shop sold
= 73 - 54
= 19 kg
Amount of pepper that both shops sold
= 2 x 19
= 38 kg
Answer(s): 38 kg
