5 u |
3 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 = 72
1 u = 72 ÷ 3 = 24
Mass of pepper in Shop B in the end
= 2 u
= 2 x 24
= 48 kg
Mass of pepper that each shop sold
= 64 - 48
= 16 kg
Amount of pepper that both shops sold
= 2 x 16
= 32 kg
Answer(s): 32 kg
