Answer:
A
Step-by-step explanation:
The percentage of lemon in the juice is 10%
The percentage of water sugar is (100-10)=90%
The quantity of lemon in 20 liters of sugar water will be:
amount=(percentage of lemon)/(percentage of sugar water)×(amount of sugar water)
=10/90×20
=2 2/9 liters
5/6......5 out of 6.......using division, it is 5 divided by 6 = 0.833
