2 u |
7 u |
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
= 7 u - 2 u
= 5 u
5 u = 80
1 u = 80 ÷ 5 = 16
Mass of pepper in Shop K in the end
= 2 u
= 2 x 16
= 32 kg
Mass of pepper that each shop sold
= 58 - 32
= 26 kg
Amount of pepper that both shops sold
= 2 x 26
= 52 kg
Answer(s): 52 kg
