Dear all,
I am glad to share this information.
I have collected these questions and answers from the emails in the group only. For 3-4 questions only, I have found the answer with the help of my teachers, so keep in mind that these answers may not be 100% correct. Try to solve it yourself.
1. You are given two candles of equal size, which can burn 1 hour each. You have to measure 90 minutes with these candles. (There is no scale or clock). Also, you are given a lighter.
2. Try the similar problem to measure 45 minutes.
3. You are given a thermometer. What can you do with this without measuring the temperature?
4. How is it possible to place four points that are equidistant from each other?
5. You are given a cake; one of its corners is broken. How will you cut the rest into two equal parts?
6. How will you recognize the magnet, magnetic material, and non-magnetic material?
7. If one tire of a car suddenly gets stolen, and after some time, you find the tire without the screws, how will you make your journey complete?
8. How can you measure a room's height using a thermometer?
9. What is the height of a room if after entering the room with a watch, your head strikes a hanging bulb?
10. What is the color of a bear if it falls from a 1m height in 1 second?
11. How will you measure the height of a building when you are at the top of the building? And if you have a stone with you.
12. How would you catch and receive a ball in the same direction?
13. 25 statements are given. Some tell the truth, some are false, and some are alternators. Find out the true statements.
14. Can you make 120 with 5 zeros?
15. There are three people A, B, C. Liars are of the same type, and truth-speaking people are of the same type. Find out who is speaking truth and who is speaking false from the following statements.
16. 5 swimmers A, B, C, E, F, and many conditions of their positions. The question was to find who was between E & D.
17. In a race, you drove the 1st lap with 40 km/h, and in the second lap, at what speed must you drive so that your average speed must be 80 km/h?
18. You have to draw 3 concentric circles with a line passing through their center without lifting a hand.
19. A rectangular paper is there. At a corner, a rectangular size paper is taken from it. Now you have to cut the remaining paper into two equal halves.
20. Value of (x-a)(x-b)...(x-z)
21. There are 9 coins. 8 are of 1 gm and 1 is of 2 grams. How will you find out the heavier coin in a minimum number of weighings, and how many weighings will it need?

As an HR expert, I'd like to clarify that these interview puzzles are often used to assess problem-solving skills, creativity, and critical thinking of candidates. While the answers may vary, the key is to approach each question with logic and reasoning. Here are some practical approaches to a few of the puzzles mentioned:
1. Measuring 90 minutes with two candles: Light both ends of one candle and one end of the other candle simultaneously. When the first candle burns out (30 minutes), light the other end of the second candle. It will take another 60 minutes for the second candle to burn completely.
2. Measuring 45 minutes: Similar to the above method, light one end of the first candle and both ends of the second candle. The first candle will burn out in 30 minutes, and at that point, the second candle will have 30 minutes of wax left. Light one end of the second candle to get 45 minutes.
3. Using a thermometer creatively: You can use a thermometer as a makeshift timer by dropping it on a hard surface. The sound it produces upon hitting the surface can be used as a time indicator.
These are just a few examples, and I encourage you to think creatively and logically to solve the rest of the puzzles. Good luck!
