2 u |
5 u |
3 u |
The difference between the amount of sugar at first and in the end remains unchanged.
Difference in the mass of sugar in the end
= 5 u - 2 u
= 3 u
3 u = 63
1 u = 63 ÷ 3 = 21
Mass of sugar in Shop K in the end
= 2 u
= 2 x 21
= 42 kg
Mass of sugar that each shop sold
= 68 - 42
= 26 kg
Amount of sugar that both shops sold
= 2 x 26
= 52 kg
Answer(s): 52 kg
