If Kylie drank 35% of 400mL, then she would have consumed 140mL of water.
If Eugenia drank 45% of 350, then she would have consumed 157.5mL of water.
Using this information, we can conclude that Eugenia definitely drank more water than Kylie.
We know this because of this reasoning:
45% of 350 = 157.5
35% of 400 = 140.0
140 < 157.5
This statement is true, so Eugenia drank more water than Kylie.
