A chemist mixes two liquids 1 and 2 – Video
Q. A chemist mixes two liquids 1 and 2. One litre of liquid 1 weighs 1 kg and one litre of liquid 2 weighs 800 gm. If half litre of the mixture weighs 480 gm, then the percentage of liquid 1 in the mixture, in terms of volume, is?
70
80
75
85
Answer: 80
Solution:
Solution: weight of half litre of the liquid 1 and liquid 2 will be 500 and 400 gm respectively.
So required ratio of liquid 1 an 2 in mixture =(480n-400)/(500 -480) =80/20 = 4:1
So the percentage of liquid 1 in the mixture= 4/(4+1) *100 = 80
