Christina and Ivan made 8 litres of lemonade for a party.
Christina drank 10% of the lemonade she made and Ivan drank 20% of
what he made. Altogether, they drank 800 ml of lemonade. In the
end, Ivan still had 0.9 litres of lemonade more than Christina. How
many litres of lemonade did Ivan make at first?
Tried working it but dun think i'm able 2 get any logical
answer. Pls help:)
The question is wrong.
Steps
1. Christina
l 1 unit
l
]
] 8 - 0.8 = 7.2 litres
Ivan l 1
unit l 0.9 litres
l
]
2. 2 units = 7.2 - 0.9 litres = 6.3
litres
1 unit = 6.3/2 = 3.15
litres
3. After christian drank 10% of
the lemonade that she made, she will have 3.15
litres left.
So, she should have 3.15/0.9 = 3.5 litres at first
4. After Ivan drank 20% of the
lemonade that he made, he will have 3.15 + 0.9
= 4.05 litres left.
So, he should have 4.05/0.8 = 5.0625 litres at first.
5. When 3.5 + 5.0625 litres = 8.5625
litres ie we do not get the 8 litres at first.
6. Hence, the question is wrong or TS
have typed the question wrongly.
