Step 1: 100 units coffee cup 1/100 tea cup 2
Step 2: 25 units in a teaspoon so end up with 75 units coffee in cup 1, 125 in cup 2, 25 of which are coffee (4/5 units are tea)
Step 3: Teaspoon of 25 units from the Cup 2 and this teaspoon is 4/5 tea, so 20 units tea, 5 coffee. Cup 1 is now 80 units coffee and 20 tea. Cup 2 after removal of its teaspoon is 80 units tea and 20 units coffee, so first response is right; they're exactly the same.

Here is the question I would ask...who mixes tea with coffee and vice/verse?

No, Asians are smarter on average by 6 points than whites.

While I wouldn't doubt that on average, asians may test better than whites, there is more to it than just testing. American schools provide more well rounded individuals as a whole. Sure the asians may nail their math tests and maybe violin recitals. But chances are this person is a social retard and will have no business sense whatsoever. Of course China would prefer these kinds of individuals, you can place them in a job and have them develop nuke's and design buildings (or a foxconn slave factory).

I've been in a university setting for 8 years and have met countless asian undergrads/graduate students. I imagine these students are among the best and brightest that the country has to offer. Yes they are smart and often set the curve in the class. Well they better set that curve, because school is all they do. They live on campus, they don't have jobs, they don't have friends, they don't have any social lives at all. They spend their days in the library studying.

All the whities on the other hand have full or part time jobs. They have families and family obligations. They have friends and social obligations. They have a role in their community and are actively engaged in living life

I wouldn't say they are smarter at all. I would say their work ethic is stronger and their desire to not shame their family is greater.

It's a cultural difference of live to work vs work to live.

Intelligence is not just by nature - it is largely by nurture. It doesn't matter if you are Einstein level, if you are kept in the basement until you're 18 years old and never taught language, your IQ will never reach triple digits.

Similarly, we all tend to become stupider and stupider as we get older and start specializing in work and stop using calculus, learning new things etc.

The fact that Asian countries like China teach Calculus in the first years of High School (and often earlier), rather than last (I took AP Calc in Junior year and senior year), pretty well indicates how much learning is stuffed into brains.

The IQ follows.

Mixed up my coffee and tea lol.

They would be the same amount of tea in the coffee as coffee in the tea, however Shawn's "they are exactly the same" was the misleading part.

No they would not

...you can call a spoon any volume as long as it's less than a cup.

Concentration = n of additive / Volume total

Say a spoon is 10 and cup is 100

Coffee in tee cup = 10/110 = .092 lets call it .092 molar coffee

which you then put back into coffee cup

Tea in coffee cup = (10 - 0.09) / 100 = 0.099 molar Tea

I would say for 99.9% of the population you are completely right, nurture dictates your smarts, hence the average asian 6 point dominance (their culture stresses maths skills while ours stresses social normality). For that fraction of a percent, however, they will just have it. Doesn't matter if they're raised by dogs or the queen of england. The number of these special individuals will correlate directly to the size of the population. These are the people with 140 IQ. A country like china has to know that based on statistics alone they have a huge edge over most other countries because of their population. The hard part is filtering to these individuals.
 
100 units of coffee
100 units of tea

10 units of coffee goes in tea

now you have
90 units of coffee
and
100 units of tea, but now also 10 units of coffee
Now that means -> 110 units of tea+coffee (10 parts tea, 1 part coffee)


Where we at?
90 units of coffee in one cup
110 units of tea+coffeeA (10 parts tea, 1 part coffee)

Take 10 units of tea+coffeeA (10 parts tea, 1 part coffee) and put it in the 90 units of coffee cup

now you have

90 units of coffee + 10 units of tea+coffeeA(10 parts tea, 1 part coffee)
100 units of tea+coffeeA

So what does that mean...

Well, it means you have:
90 units of coffee in one cup, but also ((10/11)*10) units of tea AND ((1/11)*10) units of coffee.
100 units of tea+coffeeA (10 parts tea, 1 part coffee)

Let's dew dah math?

90 units of coffee originally, 9.0909 units of tea, and 0.9090 units of coffee.
90.9090 units of tea and 9.0909 units of coffee.

Totals
90.9090 units of coffee and 9.0909 units of tea in one cup.
90.9090 units of tea and 9.0909 units of coffee in the other cup.

It's dah same.

I heard that Google does this - random intelligence rather than asking about your specific trade.

A few oil companies pulled tests like this as well. My brother was asked a question like:
Suppose you have 2 equally sized cups. One is full of coffee, one is full of tea. If a spoon full of coffee is added to the tea, the tea is mixed, then a spoon full of tea+coffee is added to the coffee, is there more tea in the coffee or is there more coffee in the tea?

I'm trying to think of how this was solved. Assume each cup has a volume of 10 units and a spoon is 1 unit. Adding 1 spoon of the coffee into the tea would mean the tea cup has 11 units of volume, 1 of them is coffee (1/11). Spoon once back into the coffee cup and the amount of coffee in the tea cup would be (1/11 concentration)*(10 volume) = 0.909 units . The tea in the coffee cup would then be (1 volume)*(10/11 concentration) = 0.909 units.
The answer is that they are exactly the same!

What is the density of coffee? What is the density of Tea? A cup is typically a volume measure (240 ml), therefore the weight of each will not necessarily be the same... I am not American so don't use cups...

What size is the spoon? Is the same spoon used both times? Is the person using the spoon capable of reproducibly transferring the same volume each time?

Assuming that the densities are the same, and that the same spoon (of less than 100% volume) is used perfectly for both transfers you will end up with the same concentration in each.

Fixed. You rounded wrong, plus you forgot to convert from "Molar" (it's percent) to units volume (x10).

Math Fail.

Well done youngling... and you also just proved 0.9999... = 1.

So if the Tea was on a treadmill, would it take off? What about the coffee? What if you replaced the treadmill with a turntable? Is .99999... cup of tea == 1 cup of tea?

No, no, no, and yes.

It's engineering, the details are important.

In this example the details are also important.

Spray dried "instant" coffee can have a density of around 0.22-0.30 g/cm³, roast beans are 0.35-0.38g/cm³ , while tea can be 0.48-0.53g/cm³. Thus using a volume measure such as a spoon means that you transfer a greater weight of tea... but its past midnight and I don't want to work that one out...

The spoon part is also important, as what type of spoonful you use determines the accuracy, if you use heaped spoonfuls the answer is anybodies guess as they aren't accurate.

Now the question may have stated additional parameters, but none were specified here...

I don't know man - you put a cup of tea or coffee on a treadmill and you're going to have airborne hot beverage when it hits the end. 😉 The turntable depends on how fast it's spinning.

It's not intended to be engineering, it's math. It's a job interview question. The beverages don't matter, the spoon doesn't matter - you're expected to assume that the liquids aren't different in a meaningful way and the spoonfuls are identical and contain a homogenous mixture. If you gave that kind of answer in a job interview you'd probably get mixed reactions - one interviewer might admire your attention to details, another might think you're missing the forest for the trees. I think the safe bet is to give the answer they're expecting and clearly explain your thought process.
