## What strategy would ensure that you drink 3 bottles of milk within 24 hours? ### Solution

This is a tricky interview question to get hired at Google.

Let’s solve the problem.

Hour 0 : feed the rat bottle one.

Hour 1 : feed the rat bottle two.

Hour : feed the rat bottle three.

You will get the answer when you time 10 hours after each feeding which will inform you about the poisonous bottle.

If the rat lives past hour 12, you will know it is bottle four .

Mathematically, you should get an answer in 12 hours.

You can also get solutions by using less than 1 hour in the previous steps.

Do you think that we have solved the problem ? No that’s not true, at the end you wouldn’t have 3 complete bottles, as the rat would have drunk a little bit from each tested bottle. So you’d have less than 3 bottles.

That was the trick! It is not easy to get hired at Google.

Mathematics reveals its secrets only to those who approach it with pure love, for its own beauty.

### The Beauty of Mathematics : It Can Never Lie to You

Mathematics is the queen of the sciences.

#### Carl Friedrich Gauss

To those who ask what the infinitely small quantity in mathematics is, we answer that it is actually zero. Hence there are not so many mysteries hidden in this concept as they are usually believed to be.

#### Leonhard Euler

There is geometry in the humming of the strings, there is music in the spacing of the spheres.

#### Pythagoras

Today’s scientists have substituted mathematics for experiments, and they wander off through equation after equation, and eventually build a structure which has no relation to reality.
