THE EGG QUESTION

Let x be the answer we want, the number of drops required.

So if the first egg breaks maximum we can have x-1 drops and so we must always put the first egg from height x. So we have determined that for a given x we must drop the first ball from x height. And now if the first drop of the first egg doesn’t breaks we can have x-2 drops for the second egg if the first egg breaks in the second drop.

Taking an example, lets say 16 is my answer. That I need 16 drops to find out the answer. Lets see whether we can find out the height in 16 drops. First we drop from height 16,and if it breaks we try all floors from 1 to 15.If the egg don’t break then we have left 15 drops, so we will drop it from 16+15+1 =32nd floor. The reason being if it breaks at 32nd floor we can try all the floors from 17 to 31 in 14 drops (total of 16 drops). Now if it did not break then we have left 13 drops. and we can figure out whether we can find out whether we can figure out the floor in 16 drops.

Lets take the case with 16 as the answer

1 + 15 16 if breaks at 16 checks from 1 to 15 in 15 drops
1 + 14 31 if breaks at 31 checks from 17 to 30 in 14 drops
1 + 13 45 .....
1 + 12 58
1 + 11 70
1 + 10 81
1 + 9 91
1 + 8 100 We can easily do in the end as we have enough drops to accomplish the task


Now finding out the optimal one we can see that we could have done it in either 15 or 14 drops only but how can we find the optimal one. From the above table we can see that the optimal one will be needing 0 linear trials in the last step.

So we could write it as

(1+p) + (1+(p-1))+ (1+(p-2)) + .........+ (1+0) >= 100.

Let 1+p=q which is the answer we are looking for

q (q+1)/2 >=100

Solving for 100 you get q=14.
So the answer is: 14
Drop first orb from floors 14, 27, 39, 50, 60, 69, 77, 84, 90, 95, 99, 100... (i.e. move up 14 then 13, then 12 floors, etc) until it breaks (or doesn't at 100)

1. How many children are born every day?

MissTechy:
2. If you have 2 eggs, and you want to figure out what’s the highest floor from which you can drop the egg without breaking it, how would you do it? What’s the optimal solution?

MissTechy:
3.You have 100 coins laying flat on a table, each with a head side and a tail side. 10 of them are heads up, 90 are tails up. You can’t feel, see or in any other way find out which side is up. Split the coins into two piles such that there are the same number of heads in each pile.”

MissTechy:
4. There are three boxes, one contains only apples, one contains only oranges, and one contains both apples and oranges. The boxes have been incorrectly labeled such that no label identifies the actual contents of the box it labels. Opening just one box, and without looking in the box, you take out one piece of fruit. By looking at the fruit, how can you immediately label all of the boxes correctly?

blessedvisky:

1)children are born only once, not everyday
2) Eggs DO NOT break floors.
3)
4)
5)
so am I correct or not so far @misstechy

MissTechy:
If you are an active reader on MissTechy .com you'd remember when I asked if you had what it took to work at Google, In my opinion, if you can work at Google, you can work anywhere – here’s something similar to that.

I saw this Interview Questions on Glassdoor and I just felt it might be very useful to some of us given that most companies especially in Nigeria like copying these big tech guys. We all know that Apple is one of the biggest Tech companies in the World and to get a job there wouldn’t be so easy.

Glassdoor decided to make this easy by providing some questions Apple Inc uses to select their employees – I would be revealing 3 questions here that I feel are more brain tasking and require more brain knowledge. Is your brain equipped to answer these Apple’s Job Interview Questions? If Yes? Let’s do this
1. 1above
2. Drop one egg to roll to the higher point
3. Top/up is where d head and tail face
4. Let assuming I opened orange box then lighter among is apple Y the heavier box is mix box










So who can answer any?

THE EGG QUESTION

Let x be the answer we want, the number of drops required.

So if the first egg breaks maximum we can have x-1 drops and so we must always put the first egg from height x. So we have determined that for a given x we must drop the first ball from x height. And now if the first drop of the first egg doesn’t breaks we can have x-2 drops for the second egg if the first egg breaks in the second drop.

Taking an example, lets say 16 is my answer. That I need 16 drops to find out the answer. Lets see whether we can find out the height in 16 drops. First we drop from height 16,and if it breaks we try all floors from 1 to 15.If the egg don’t break then we have left 15 drops, so we will drop it from 16+15+1 =32nd floor. The reason being if it breaks at 32nd floor we can try all the floors from 17 to 31 in 14 drops (total of 16 drops). Now if it did not break then we have left 13 drops. and we can figure out whether we can find out whether we can figure out the floor in 16 drops.

Lets take the case with 16 as the answer

1 + 15 16 if breaks at 16 checks from 1 to 15 in 15 drops
1 + 14 31 if breaks at 31 checks from 17 to 30 in 14 drops
1 + 13 45 .....
1 + 12 58
1 + 11 70
1 + 10 81
1 + 9 91
1 + 8 100 We can easily do in the end as we have enough drops to accomplish the task


Now finding out the optimal one we can see that we could have done it in either 15 or 14 drops only but how can we find the optimal one. From the above table we can see that the optimal one will be needing 0 linear trials in the last step.

So we could write it as

(1+p) + (1+(p-1))+ (1+(p-2)) + .........+ (1+0) >= 100.

Let 1+p=q which is the answer we are looking for

q (q+1)/2 >=100

Solving for 100 you get q=14.
So the answer is: 14
Drop first orb from floors 14, 27, 39, 50, 60, 69, 77, 84, 90, 95, 99, 100... (i.e. move up 14 then 13, then 12 floors, etc) until it breaks (or doesn't at 100)

ollyruffy:
1. To answer this, you need some statistical data such as the estimated world population over a certain period.

Say over 1 year period, divide the difference in population by 365.


2. You need to know or have or device a mean to measure the amount of force required to crack the shell of one egg.

Then you will calculate the impact force that will be generated on the egg when you drop it from each floors. To calculate this force, you need to know the weight of the egg and heights of each floor.

Then, compare the force to crack the shell to the impact forces of each floor.

3. In this case, you have to make use of sound wave or energy. You need to push each of the coins on the table and listen to the sound notes produced. If ordinary ear cannot differentiate these notes. Then you need an electronic sound analyser to record and analysis sound waves coming from each of the coils.

4. Here, you to know the quantities of fruits in the bag and weight of one orange and one apple.

If you know these, you can be able to guess the boxes correctly.

In summary, the questions lack required data to provide scientific answers.

qbd2:
1.Count 50 coins and place one side, count another 50 and place another side.
2. Say for example d apple box is labelled orange, the orange is labelled orange and apple, and the orange and apple is labbeled apple.
Say now I open the box labelled orange and I find an apple. Ill then know that the box labbeled apple must contain another fruit ( assumingly orange). Don't know d rest.
3. At least one child.
4. Go to d 22nd floor and drop the first egg, d result will teach u whether or not to throw d second egg.

1; as much babies as to fill up for people who die everyday

KMJY:
this answer has scatter my brain even more than the the question. Let's go on a recess. We'll reconvene on the May, 29.

somegirl1:
These can't be interview questions but here goes.

None, we born once.


The egg or an egg?


separate into 50 on either sides. All coins have a head on one side.


Feel the contents. If items feel different - mixed box. If all same, pick one label box as what you picked.

Nasri228:
xo non of u cn ansa any of dis question

no1 question x logical n simple

dey knw vry wel nobdy can say de exact number of babies born daily..xo dey only wnt u to use ur logical sense

no1 ansa is two babies(i.e boy n girl)....tke me to anywere
