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 = 70
1 u = 70 ÷ 5 = 14
Mass of pepper in Shop M in the end
= 2 u
= 2 x 14
= 28 kg
Mass of pepper that each shop sold
= 76 - 28
= 48 kg
Amount of pepper that both shops sold
= 2 x 48
= 96 kg
Answer(s): 96 kg
