BRAIN TEASER!
Suppose we put down two cups in front of you. One of the cups is filled with tea and the other one with coffee. Now we ask you to take a spoonful of tea and mix it with the coffee. At this moment, the coffee cup has a mixture of tea and coffee. You have to take that mixture (spoonful) and add it back to the tea. Can you now tell if the cup of coffee has more tea or the cup of tea has more coffee?
◆ Proper explanation needed.
Answers
Both are same.
We added spoonful of tea to coffee and then spoonful of mixture back in tea cup.
Thus, if any amount of tea is missing from the tea cup, it's now in the coffee cup and any amount of coffee missing from the coffee cup is now in the tea cup.
There is no change :)
Answer:
The levels of liquids in both cups must be unequal after adding 1 scoop of tea to coffee. Whatever is missing from the tea cup is now in the coffee cup and has been blended with the coffee. The amount of tea in a cup of coffee is unquestionably higher.
After returning a tablespoon of the mixture to the tea cup, the liquid levels in both cups should be the same. As a result, whatever cup of tea is lacking is replaced with a cup of coffee. That missing tea content has now found its way into a cup of coffee, replacing some of the coffee content!
Assume each cup of tea or coffee contains 1000 molecules. Assume 100 molecules of tea are added to a cup of coffee with a spoon. Now, a coffee cup will contain 1100 molecules, while a tea cup will contain 1000 molecules. There will be 1100 molecules in the tea, and 900 molecules in the coffee. Clearly, a cup of coffee has more tea (100 molecules) than a cup of tea (0 molecules) right now!
Let's say you're taking 100 molecules from a combination with 1100 molecules, and you're taking 70 molecules of coffee and 30 molecules of tea. That means there are exactly 100 - 30 = 70 tea molecules left in the combination. The mixture of 70 + 30 molecules is poured into a cup of tea. That's exactly 70 coffee molecules in a cup of tea.
What does this imply? 70 molecules of coffee have displaced 70 molecules of tea into a cup of coffee, ensuring that both liquids are at the same level.
We can also put it another way. In a cup of tea, 30 molecules of tea displaced 30 molecules of coffee.
Conclusion- Same amount of liquid in each cup
