### Let's say we're playing Russian roulette. The revolver has SIX barrels, THREE of which contain bullets. I give you two options: A. Spin, shoot. Spin, shoot. Spin, shoot. (For a total of three times). B. Spin once and pull the trigger twice. Which option would you pick and why?

11 réponses

I forgot to add a crucial part of the question in my original post, which is that you know that the three bullets are right next to each other. Thus, the first spin determines whether you survive, and there are two out of the six chambers that are safe to "land on," hence 1/3. In my original wording of the question, I think your chances of survival would just be (3/6)*(2/5) = 1/5. Moins

None of them, I want to live.

How about we just not play Russian roulette.

### How do you make 4 gallons from a 3 and 5 gallon jug?

10 réponses

Fill the 3 gallon jug, pour it into the 5 gallon jug, fill the 3 gallon jug again, fill the 5 gallon jug until it is full (leaving 1 gallon left in the 3 gallon jug) dump out the 5 gallon jug, then pour your remaining 1 gallon into the 5 gallon jug, then fill the 3 gallon jug and add it to the 1 gallon in the 5 gallon jug. Moins

Fill up each jug half way. 2.5+1.5=4

1. Fill the 5 gallon jug. 2. Pour the 5 gallon jug into the 3 gallon jug. (Leaves you with 2 gallons in 5 gallon jug) 3. Empty the 3 gallon jug and pour the remaining 2 gallons in the 3 gallon jug. 4. Fill the 5 gallon jug and pour 1 gallon into the 3 gallon jug (remember it will only take one gallon) 5. Viola the remaining 5 gallon jug will have exactly 4 gallons remaining. Moins

### The company is losing 1 million subscribers every month. What are the possible reasons for losing subscribers? Given the company is losing subscribers at this pace, how long can the company continue, until it starts making loss?

10 réponses

12Bn Rev Per year 9BN cost per year Customer Loss per year = 1million *12 months = 12 million customers Revenue per customer per year = 36 + 7*12 = \$120 Each year, company looses 1.44BN. = (12 million *120) To make a loss, company must loose 3BN 3BN/1.44BN = 2.083 years 2.083 years = 25 months. Moins

25 months doesn't sound right... Revenue: \$12 billion Costs: \$9 billion Profit: \$3 billion Customer lost/month = 1 million Revenue lost/month = (36/12 + 7) = \$10 * 1 million = \$10 million Break even = \$3 billion / \$10 million = 300 months 300 months / 12 = 25 years The only way I can see 25 months is if we assumed Ad Revenue is Annual and CANNOT be broken down to month average/customer. In that case Annual Revenue/Customer = 36 + (7 *12) = \$120/customer Total lost revenue/month = 120 * 1 million = 120 million Breakeven = 3 billion / 120 million = 25 months Moins

25 months

### You have a cube which is built from smaller cubes, dimensions are 10x10x10cubes. The cube fell into a bucket with red paint. How many cubes left uncoloured.

11 réponses

Cube is 10 x 10 x 10 meaning W=10, L=10 D=10. To get the total number of cubes we need to calculate the area of 1 face of the cube (L10 x W10 = 100) and multiply it by D10 = 1000 cubes inside. Now if the cube fell into a bucket with red paint the only cubes that won't be colored are those on the inside. therefore we know that a cube has 6 faces, each of them has (L10 x W10) cubes, therefore 1000 - (100 x 6) = 400 cubes won't be colored. Moins

pretty sure you've got it totally wrong

yes, it is wrong but not totally, just the calculation of the internal cubes which should have been W8 x L8 x D8 = 512 cubes not painted Moins

### How'll you find the weight of an object attached to another object without detaching them and without using any weighing machines. Both the weights are unknown

8 réponses

Cant we just see the amount of water displaced by the object and then calculate the weight? I think its easy that way, as we can control the volume immersed in water. (let it be attached in any way) Moins

by immersing them in a liquid....one by one....and checking the amount of volume displaced.......and applying principles on the liquid collected Moins

Water displacement theory seems to be nice. Since there is no information regarding how they are attached we can do the following way. catch one weighted and dip the other weight in water. Some water will be displaced. Now repaeat the same in revesrese order. i.e catch the second side and dip the other weight. Now calculate the amount of water displaced in both the cases. greater displacement - lesser water displacement. Now immerse completely both the objects and find the displacement of water. by this you can arrive at the answer Moins

### Which number is bigger: 5/6, 3/4, 4/7, 4/9, or 9/11

7 réponses

3/4, 4/7, and 4/9 are clearly smaller than 5/6 and 9/11, so they are eliminated. So which is bigger, 5/6 or 9/11? You can look at it as which is smaller, 1/6 or 2/11. 2 does not fit into 11 six times, so 1/6 is smaller. Since 1/6 is smaller than 2/11, 5/6 is larger than 9/11. Moins

Think about it this way, in 5/6 you are leaving 1/6th part out, in 3/4 you'll leave 1/4th part out.. and so on.. Try to find the smallest part you are leaving out. Moins

5/6 is the largest fraction in the set....

### How would you deal with a stakeholder who was insisting that a complex process would be the ideal solution to an existing problem?

7 réponses

nice!!

Thank You!!!

I would agreee with the first answer if we were told that the interaction occurred during a requirements meeting. What if the stakeholder was insisting while you were working on the solution? I agree that the answer should be to either propose the alternate solution and explain why it is the better approach. Moins

So true. Thanks for your comment. I would request you to share your experience as well so that we can make people aware of what goes on inside this company and they can stay away from it. Moins
