2 u |
11 u |
9 u |
The difference between the amount of flour at first and in the end remains unchanged.
Difference in the mass of flour in the end
= 11 u - 2 u
= 9 u
9 u = 99
1 u = 99 ÷ 9 = 11
Mass of flour in Shop E in the end
= 2 u
= 2 x 11
= 22 kg
Mass of flour that each shop sold
= 51 - 22
= 29 kg
Amount of flour that both shops sold
= 2 x 29
= 58 kg
Answer(s): 58 kg
