Question: A car and a bee start at points A and B respectively, with specific speeds. How many kilometers does the bee travel before meeting the car?
Answer: The bee travels for the same duration as the car, covering a distance based on its speed, which is calculated to be 260km in this scenario.
5. Cube Painting Puzzle:
Question: A cube of 10m³ volume is divided into 1000 small cubes of one cubic meter each. If the cube is dipped in paint, how many cubes are colored?

Logical And Analytical Brain Teasers In Hedge Fund Interviews
Here are 5 logical and analytical brainteasers that are commonly asked in hedge fund interviews:
1. The Light Switch Puzzle:
Question: You are in a room with three light switches, each controlling a different light bulb in another room. You can only make one trip to the other room. How can you determine which switch controls which light bulb?
Answer: Turn on one switch for a few minutes, then turn it off and turn on a second switch. Enter the other room; the bulb that is on corresponds to the switch left on, the warm bulb corresponds to the first switch, and the off bulb corresponds to the switch left off.
2. The Prisoner Hat Puzzle:
Question: Ten prisoners are lined up, and each is given a hat that is either black or white. They can see the hats of those in front but not their own. Starting from the back, each prisoner must correctly guess the color of their hat or face a penalty. How can they maximize the number of correct guesses?
Answer: The prisoners agree on a strategy where each prisoner guesses based on the number of black hats they see in front of them. By following this strategy, they can ensure that at least 9 out of 10 prisoners guess correctly.
3. The Islander Puzzle:
Question: On an island, there are 100 blue-eyed people who can see everyone else's eye color but not their own. They are told that at least one person has blue eyes, and they must leave the island if they can determine their own eye color. How many days will it take for them to leave the island?
Answer: By applying logical reasoning and understanding that everyone can see the eye colors of others, they will realize that they all have blue eyes and will leave the island on the 100th day.
4. The Two Doors Puzzle:
Question: You are faced with two doors: one leads to certain death, and the other to freedom. There are two guards, one who always tells the truth and one who always lies, but you don't know which is which. What one question can you ask to determine the correct door?
Answer: Ask one guard, "If I were to ask the other guard which door leads to freedom, what would he say?" The truthful guard will point you to the door of death, as he knows the lying guard would lie about the other guard's response, while the lying guard would also point you to the door of death to deceive you.
5. The Hat Colors Puzzle:
Question: In a room, there are three people wearing hats: one red, one green, and one white. They can see the other two hats but not their own. They are told that at least one of them is wearing a red hat. After observing each other, none can determine their own hat color. What color is each person's hat?
Answer: By analyzing the situation and understanding that no one can immediately determine their hat color, it can be deduced that the person wearing the white hat will be the first to realize their own hat color, followed by the person wearing the green hat, and finally the person wearing the red hat.
