In the question, there are two people with different percentage of drinking water from different quantities. Taking the first case of Kylie we get that he drank 35% water of 400ml Then 35% of 400 ml = (35/100) * 400 ml = (35 * 4) ml = 140 ml So Kylie drank a total of 140 ml water. Now taking the case of Eugenia we get that he drank 45% of 350 ml water. Then 45% of 350 ml = (45/100) * 350 = 1575/10 ml = 157.5 ml So Eugenia drank 157.5 ml of water. Then we can conclude that Eugenia drank more water than Kylie.
